Cisco WAN :: ASR9010 IPSLA Track Static Route And Redistribute Into EIGRP
Jun 8, 2011
Is it possible to track a IPSLA operation and if it goes down track a static route which will be removed from EIGRP process. I have read through documentation and have come stuck. I have the below configured and have shown the features installed. How would I go about getting the below static route injected into EIGRP only if the IPSLA operation in ok?
track RMB
type rtr 100 reachability
ipsla

I have an issue with my setup of a 6500 switch (12.2(33)SXI9).We have a 6500 switch with several VRF's. For a certain VRF I would like to redistribute a static route in EIGRP. After doing so I don't see the static route on my eigrp neighbor.
This is a overview of my config. I'm basically redistributing only my static route for this vrf in eigrp.
I found a similar case in which the solution was adding a metric to the static route. (eg. redistribute static route-map static-eigrp-pp metric 10000 100 255 1 1500). But the strange thing is that we don't have this issue on a similar machine (same IOS, same config setup). [code]

i wonder if i can make a backup static route for an existing link over wan using the below diagram
the Core Switch type is 3750 in both sides i`m using only static routing for all destination like
Core1:
ip route 192.168.8.0 255.255.255.0 172.10.10.30
Core2:
ip route 172.17.200.0 255.255.255.0 192.168.100.105
requirements is to track the reachibility for the core ip address from both sides & change the routing automatically to the backup tunnel line

I config the routers with EIGRP and also write Static route between two PC before remove the link between router0 and router1 , destination is reachable , but when remove this connection , packet from pc1 to pc0 will drop in a loop and never reach to destination , is it possible to have a Link state routing protocol and static route at the same network like this scenario , how to prevent loop in this topology static route is configure as bellow :
router0 <==> router 1 <==> router2 <==> router3 <==> router <==>pc1

I'm attempting to redistribute a static route into EIGRP on a 3750 switch and pass it to an upstream router, sadly however this isn't working, or at least the route isn't being recieved on the upstream router. [code]

I was reading my book when I found :
redistribute ospf 2 external 2
The book says only ospf external routes of type 2 will be redistributed.But when I tried to configure the above command on router, I was not able to configure it; there was no external or internal option available with redistribute ospf command.
Below is the output:
R2(config)#router rip
R2(config-router)#redistribute ospf 1 ?
match Redistribution of OSPF routes
metric Metric for redistributed routes
route-map Route map reference
vrf VPN Routing/Forwarding Instance
<cr>
R2# show version
Cisco IOS Software, 2600 Software (C2691-ADVIPSERVICESK9-M), Version 12.4(15)T6, RELEASE SOFTWARE (fc2)
Do we have such command for eigrp? For example If i want to redistribute only external routes from eigrp into ospf, do we have any command such as :redistribute eigrp 1 external ?I understand there is several ways to achieve to same goal however I am just curious if we could acheive the same goal using single redistribute eigrp command without any route-map.

Our current router is setup to redistribute our BGP routes into OSPF using the following code:
-router ospf 60
-log-adjacency-changes
-redistribute bgp 65199 metric 1500 metric-type 1 subnets
I want to filter down the routes so only a set of specific routes is redistributed.. we have done this in the past with EIGRP by doing a route-map / prefix-list to manage the routes passed into EIGRP.My question is I can replicate the metric and the metric-type in the route-map by doing the following: [code] Do I need to be concerned witht the "subnets" command in this design? What I understand "Subnets".When redistributing routes into OSPF, only routes that are not subnetted are redistributed if the subnets keyword is not specified. I suspect I need to add it! So my final code should look like this..

I got remote offices connected to our DataCenter some via MPLS and some via VPN terminated on Cisco ASA 5510. I am running OSPF on LAN and BGP for MPLS sites. To have reachability to VPN remote offices I added 'redistribute static in OSPF' and to have rechability to sites connected via metro link i added 'redistribute connected'

I have an 877 router which has a DSL WAN interface. The DSL service at this site is unreliable, so the company have purchased a separate 3G router to be used as a backup. This device maintains 3G connectivity at all times and has a static IP on the internal subnet (for arguments sake let's say 10.0.0.253).
What I want to do with the Cisco router is to track the DSL interface and if it is up, install a default route pointing to it. If it is down, I want the default route to be the 3G router.
I am thinking the best way to do this is to set up a track and then set 2 default routes; one which is installed if the tracking is up, the other has a higher admin distance and points to the 3G router and thus should only be used if the track is down. For example:
track 10 interface Dialer0 ip routing
delay down 30 up 30
ip route 0.0.0.0 0.0.0.0 Dialer0 track 10
ip route 0.0.0.0 0.0.0.0 10.0.0.253 100
Is this likely to work or is there a better way to do it?

I have an ASA 5520 connected to a Cisco 6509E, and we're turning up EIGRP between the two. The problem that I'm running into is that there a few static routes (including a 0.0.0.0) on the core that's being redistributed into the EIGRP AS, and I need to block this from being propagated to the ASA. The ASA only has the capability to use an ACL in conjunction with a distribute-list, and I can't find a way to filter the default route (0.0.0.0 /0), while allowing everything else.

I have a customer with a primary datacenter and DR datacenter, that has a P2P 100Mbps link connection between them. At the primary Datacenter there will be a Nexus 5596U with a L3 card running EIGRP, it will have three connections, one nothbound to the Internet not a problem, the other is north bound to an MPLS SP managed ISR router. Both datacenters will have MPLS SP managed ISR router, the MPLS service provider will be redistributing BGP into EIGRP from their ISR routers at both datacenters. This means we will learn external EIGRP routes with an AD of 170.
Connected to my 5596 southbound will be the SAN for the EMC storage traffic, the DR also has a SAN with EMC storage as well. The 100Mbps P2P link is primarily for replication traffic.
Since the Nexus 5596U with L3 module doesn't support PBR I have to figure a way for replication traffic to prefer the 100Mbps P2P link vs the MPLS cloud. I was thinking of running iBGP over the P2P link with the Nexus 5596 being a route reflector and it's iBGP peer which will be a Catalyst 3750X at the other end of the P2P link being the route-reflector client. That way both iBGP peers will exchanged learned routes.
I have to come up with a way for the replication traffic that comes sourced from the IP addresses of the EMC/storage to prefer the P2P link which will have an AD of 200 from iBGP in the routing table vs the external EIGRP traffic that has an AD of 170 in the routing table. All other traffic will route normally across the MPLS cloud. All other traffic will include client server traffic as there are application servers that sit south bound of the Nexus 5596, the client traffic will come inbound to the datacenter via the MPLS cloud.
I don't have a Nexus 5596 to do a mock lab. My thought is to redistributed connected with a route-map in EIGRP on the Nexus 5596 with a two match statements then set the IP next hop to the IP of the 3750X. I would need to select only replication traffic, so I was thinking if I can match on vlan and next-hop then my set command would be the next-hop of the 3750X.

I have a mixed WAN environment with both eBGP and EIGRP routes. The BGP routes should always take precedence, when they exist. If no BGP routes exist I want the router to fail over to using the EIGRP routes. So far, this works fine.
The problem is, when the BGP route again becomes available (and the associated entry appears in the "sh ip bgp ... received-routes" output) the router is NOT relinquishing the EIGRP route. It remains in effect, showing as a "D" route int the route table even though there is a better ("B") route available. If I bounce EIGRP or the interface associated with it, the EIGRP route disappears and the BGP route reasserts itself, and everything will run correctly until the next time the BGP route disappears due to maintenance, line failure, etc.
My router is (C2900-UNIVERSALK9-M), Version 15.3(1)T
Here's the associated config
interface Tunnel101
description VPN backup WAN interface
bandwidth 7168
ip address 192.168.75.1 255.255.255.0

In EIGRP, if a router loses the successor to a route, and it has no FS, it goes active (starts asking all neighbors if they have a successor for that route).But if the neighbor did have a successor, shouldn't they have pro-actively told us about it when they learned it (so we already have it as the Feasible Successor?).

I have a 3750 at a branch running EIGRP connected to two routers that both have configured:
access-list 1 deny 0.0.0.0
access-list 1 permit any
access-list 2 permit 0.0.0.0
access-list 2 deny any
router eigrp 1distribute-list 1 out FastEthernet0/0distribute-list 2 in FastEthernet0/0
Due to this recently applied config the switch become unreachable from the outside and cannot ping anything. Everything connected to it works fine. I was able to remote into it from a switch behind it and noticed that the 3750 has no default route in the routing table. I do see a default route in the eigrp topology table. How to make the switch learn a default route maintaining the existing configuration on the routers.

I'm trying to create a route-map for an EIGRP Distribute list on a N7K, the goal is to not advertise a 10.0.0.0/8 and 172.31.30.20/32 networks out a link to a remote site while permitting all other traffic to the internet (default). I configured the ACL/route-maps below and applied them outbound on the N7K interface but no subnets at all are being received on the remote site router.
ip access-list DENY_10.0.0.0
10 permit ip any 10.244.244.20/30 <<--WAN interface network
20 deny ip any 10.0.0.0/8
25 deny ip any 172.31.30.20/32
30 permit ip any any

We are deploying a new office in the building next to our main office. The main office has a Cisco ASA 5510 behind that is a Cisco 3750 stack. In the new office we are deploying a new Cisco 3750, they will be connected via fiber cable. I have sliced off VLAN 800 as a transit link /30 with an address space of 10.249.249.1-4. The new 3750 only has two VLAN's 800 and 112 (10.112.0.0/24). VLAN 112 routes are advertised to the neighboring 3750 properly as seen in the routing tables of the 3750 stack:
D 10.112.0.0/24 [90/3072] via 10.249.249.2, 00:22:24, Vlan800
Traffic passes between all local VLANS with no issue. I found in order to get packets to pass between the ASA and the new 3750 I had to add a static route to the ASA:
S 10.112.0.0 255.255.255.0 [1/0] via 10.100.0.1, inside
My question is why is EIGRP not advertising the 10.112.0.0 network to the ASA. Here are EIGRP configs on the switches
Existing 3750 Stack
router eigrp 100
network 10.0.0.0

this is a Nexus 5596 L3 with the latest code:
It looks like the deny statement is not working as I can see all routes I am redistributing. I even did a deny on a specific route and I still see it in the routing table on another router in the autonomous system.The same below works fine on IOS platform. [code]

VPN 1841, and static nat. I have to create VPN to connect to remote network, but problem is that they already use same subnet as mine. How to configure static nat on cisco 1841 so static nat will work and address will be translated in different IP when connection trough VPN.I have address 192.168.235.1 and I want to translate to 192.168.100.1,This 1841 is border router, and all VLNAs and VLANs routing is on 3650.

Basically I have a bunch of computers that are being routed through a specific gateway in order to access a web page that is hosted internally on a separate subnet. I set up static routes on all of the computers, and they all work... except one.Here's what a route print -4 looks like for a working computer (Windows 7):
Code:
===========================================================================
Interface List
14...xx xx xx xx xx xx ......Broadcom 802.11n Network Adapter
11...xx xx xx xx xx xx ......Realtek PCIe GBE Family Controller
1...........................Software Loopback Interface 1
[code]....
Both of these stations are running Windows 7.So essentially what I am trying to do here is route all traffic to the 10.zzz.zzz.0 subnet through the 10.xxx.xxx.147 gateway. Everything else should go through the 10.xxx.xxx.230 gateway. This is the intended behavior, and again it is working everywhere but that one station.

I have a new Cisco 819 router wtih Verizon 3G built in. I want to use this router to provide 3G backup Internet access for a customer kiosk. The 3G is perfectly stable when I use it as a primary, static routed connection. When I use a floating static route, the link goes up and down constantly. The 3G link works for a about 20- 30 seconds, then goes to reset, down, then dials up and reconnects.

I have a nat and vpn setup on my Cisco 2801 router.Everything is working as expected except the NAT. I have a single static nat translation but it only works for inbound and not outbound. Going outbound, it uses the default overload nat address of the outside interface. [code] I want to add another mailserver. But I fear if one mailserver were to get black-listed, they would both be reporting there ip address as the same address (the one on the ethernet interface) which would blacklist both mail servers.Again, inbound nat works ok, but outbound is just using the IP of the ethernet0/0 address.

Got a problem routing trafic to my L2L tunnel...
Got an ASA5505 Sec+ with ip 10.45.10.1 on inside interface. Firmware 8.3(1). Got another Cisco router (From my ISP) with ip 10.45.10.254 - This one creates an L2L tunnel - To the 10.45.20.0/24 net.
On the 5505 ive got "route inside 10.45.20.0 255.255.255.0 10.45.10.254 1", and trafic is being directed to 10.45.10.254 as it should.
I know cause I can ping everything one the 10.45.20.0/24 net - But thats it... Cant RDP, connect to fileshare... Nothing.
When i test a PC and set it to gateway 10.45.10.254 I can access everything on the remote network. Do I need some NAT command or an access-list? I've setup AnyConnect VPN on the ASA and I can connect to both networks without any problems.

In my Lab environment in GNS I have connected two 7200 series router through fastethernet on router A I have given IP adress 192.168.10.54 and router B I have given IP address 192.168.10.53 and default route as 0.0.0.0 0.0.0.0 192.168.10.53 and when I run the command on router A it shows result as follows "C 192.168.10.52/24 is directly connected ,Fast ethernet 2/0".
So I need to know why it's showing the result of .52 at last why not .53 or .54 at last what is the reason it's showing .52 which I have not mentioned in my IP address.

We have a customer, who has the following setup:
ISP router with ip range: x.x.202.1/ 28
That is connected to a Cisco 2960 switch, that doesn't do much but:
Vlan5: x.x.202.14 /28
Port 1-12 is switchport mode access to vlan 5 There are 3 firewall's connected to the 2960
1: D-Link DSR-1000N with ip x.x.202.2 /28
gw: x.x.202.1
2: Uknown
3: Cisco ASA 5505 with ip: x.x202.7 /28
static route: x.x.202.1
Each FW have a LAN behind it. The D-Link and the unknown device are both working perfectly and clients on each subnet can connect to the internet?However when I connect the ASA 5505 to the 2960 SW with a configued static route: Route Outside 0.0.0.0 0.0.0.0 x.x.202.1 1 is says it has no route to host?
Sanitized Config for the ASA 5505 is:
hostname ciscoasa
domain-name network.local
names
!
interface Ethernet0/0
switchport access vlan 2
[code]....
If I connect the ASA5505 to the LAN of D-Link DSR-1000N and give it a static address and a static route match the D-Link LAN network, it works perfectly, however not when I connect it the the Cisco 2960 Switch

I have a Cisco 1841 with a DSL and 3G HWIC interface. I would like to setup the DSL as the primary link and then use the 3G as a backup interface. I am trying to accomplish this using the Floating Static routes with SLA object tracking.
I have tried various options, like having two tracked routes, one tracked route, changing administrative distances, multiple SLA's, etc etc.
My problem basically is that when the DSL (Dialer0) goes down and the 3G (Cellular0/1/0) takes over, that the SLA never changes back when the DSL is available again, so that the DSL can take over as the primary link again. [code]

I am setting up a remote site to provide a backup internet circuit for outbound traffic. Everything is working from the main site by redistributing a static route and using default-information originate within BGP to my MPLS provider.Now on the remote site I setup a static route with an AD of 250 which is higher than the AD of 20 we are getting from the main site over the MPLS network. When the route come up BGP uses the default route from the main site and everything works fine. When I clear the BGP routes at the main site the backup site installs the static route with a higher AD. The problem is when the BGP route comes back up the static route is not getting removed. From looking at some other posts it seems that the redistributed local route is still preferred by BGP. They mentioned setting the weight to 0 in a route map which I tried but I am not getting the results of removing the static route and using the BGP route.Remote site router config: router bgp 65011.
