Cisco Switching/Routing :: ASR 1001 - Trace Route / HSRP / VRF

Mar 24, 2013

when i make a trace route on an ASR 1001 router to 172.23.30.7 I get the following output:
 
VRF info: (vrf in name/id, vrf out name/id)
  1 192.168.99.192 0 msec
    192.168.99.191 1 msec
    192.168.99.192 0 msec
  2 172.23.30.243 1 msec 1 msec 1 msec
  3 172.23.30.7 1 msec 1 msec 1 msec
 
Is there a loop between 192.168.99.191 and .192 (this are two routers with hsrp .190) or is this normal behavior when using trace route on an asr 1001?

Cisco :: EIGRP / Static Route In Same Topology?

Oct 13, 2012

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

Cisco WAN :: ASA 5520 EIGRP Route Filtering?

Feb 26, 2012

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.

Cisco WAN :: Nexus 5596U EIGRP Route Preference

May 9, 2012

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.

Cisco WAN :: C2900 - Route Selection When Using EBGP And EIGRP

May 22, 2013

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

Cisco :: EIGRP - If Router Loses The Successor To Route And It Has No FS It Goes Active?

Mar 11, 2012

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?).

Cisco Switching/Routing :: EIGRP Default Route 3750

Jun 20, 2012

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.

Cisco Switching/Routing :: Create A Route-map For An EIGRP Distribute List On A N7K?

Apr 26, 2012

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.

Cisco Switching/Routing :: EIGRP Route Advertisements Not Making It To ASA 5510?

Mar 11, 2012

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

Cisco Switching/Routing :: 6500 Redistribute Static Route In Eigrp With VRF

Feb 19, 2013

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]

Cisco WAN :: ASR 1001 Interface For Vrf Forwarding

Cisco WAN :: ASR 1001 Router Link Doesn't Come Up

Mar 7, 2013

We have an existing WAN connection from a Cisco 2821 router to Time Warner with a single mode fiber connection using the following SFP:We have a ASR 1001 router configured to replace the 2821 router.  When I connect the fiber into the ASR 1001 router the link does not come up.  I have used the above SFP without success and the following SFP.I have seen Cisco documentation that only certain SFP modules are compatible with ASR router, but I believe the second SFP I listed is compatible.  As a test, I connected my ASR router to a 3750 switch using long haul SFP modules on each end so I know the SFP module works.  The only downside to this test is I only had a multi mode patch cable.  Are there specific settings on the ASR interface that need to be set to allow this connection?

Cisco WAN :: ASR 1001 Unexpected Output Drops

Jan 31, 2012

I have an issue with an ASR 1001. The problem occurs with MQC shaping applied to a gigabit interface in the outbound direction. The CIR of the provider we are using is 100Mb/sec, so we are shaping to that value. However when reported traffic levels are about 60Mb/sec, we see a steady increase in output drops. [code]
 
I have also tried increasing the hold queue, however this does not work with the drops. Increasing the shaping rate to 200Mb/sec gets rid of almost all the drops (not quite all!) but is not what we need. I think that we should see some drops when rates spike above 100mb, however the amount we are seeing seems excessive?

ASA-10.10.10.2/19 -- ASR-10.10.10.1/19. I know the 2nd interface on the ASR will need to be on a different network segment then the first connection (10.10.10.1/19). What would be the best way to segment this out with out breaking up my /19?
 
Run /30 segments for each interface? Use a VLan ?
