I want to leak default internet route to CE VRF as common service.Since we having two ASBR, can I point next hop to PE itself instead of either of the ASBR?I tried to point NH to loopback of the PE itself but it failed.

I've enabled antispoof on all interfaces on asa 5510.If you start a traceroute to a network on the default route, everything works, since replies comes to an interface with route 0.0.0.0/0 defined.If you start a tracer route to a network that is NOT on the default route (let's assume coporate MPLS), you only get response from first carrier router, the other are discarded because of anti spoof violation.
I have ICMP inspection and icmp-error inspection enabled.
I'm working on a practice lab and am having the following issue. I have a customer router connected to two different ISP routers. Each ISP router must advertise a default through BGP to the customer and one of the default routes must be preferred over the other. Given if the preferred route interface is shut down the other default route is inserted into the routing table and when the preferred default route interface it turned back on that path is used again. The catch is I cant alter the customer router only the the two ISP devices. I tried doing some route maps but I'm lost. I have deleted all my route maps and have posted the BGP portion of the ISP routers.

Looking through the SPROUTE course material they state on several occasions that an ABR will announce a default route in to a standard NSSA area, same as a stub area, because LSA5 external routes are not allowed.

View 1 Replies View RelatedI bought a WRVS400N v2 to be used as an access point. Currently it is hooked up on my switch via a trunk port and is able to communicate with my gateway. Whenever I try to access an IP subnet other then the local IP address of the WRVS, I get a network unreachable error. To fix this for my local networks, I added the appropriate static route to cover my local LANs and that seems to work now. I tried to add route 0.0.0.0/0.0.0.0 using the web interface for internet access, but somehow it does not recognize this as a default route (quad zero!?). Does any know how I can set the default gateway in this router? Maybe, but hopefully not, I have to use the WAN port to create some kind of uplink and use one of the LAN ports to connect using the trunk port and route traffic for the clients over the WAN port .
View 1 Replies View RelatedI 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?

View 4 Replies View RelatedI am having a strange requirement. actually I am not sure it is strange or not. I am having ASA5510 with 8.4 sw version. Currently one ISP is connected to it. It is working fine. We have some servers that are directly connected to internet using another ISP connection. These servers having public IP addresses configured on their LAN settings. I need to move these servers in to the DMZ zone.
When i connect it to the ASA's DMZ zone,servers will get internet through the first ISP that is already configured on ASA. But i need to NAT the DMZ servers with the IP address provided by the other ISP, which even not configured on ASA.
So what should i do? In short my requirement is
1) need to NAT the server with the IP address provided by another ISP
2) Also note that the default route is configured for the first ISP only in ASA
so Do i need to configure another default route? Do i need to make it with larger AD? So i do it will act as the secondary route only.
I need to make the ASA up and running for two ISP, and servers in the LAN should be able to NAT with the IPs of first ISP and ,the servers in the DMZ zone should be able to NAT with the public IP of the new ISP.
In case customers buy IP transit(there is a BGP session between ISP and customer), they often ask for default route and for example prefixes from local internet-exchanges. What is the advantage to have default route + certain smaller(for example /17, /18 and /24) prefixes?

View 5 Replies View RelatedWe have a Nexus 7010 running version 6.1(2).
I'd like to use IP SLAs and object tracking to define static routes for specific source/destination traffic across some WAN links we have. I've done this in IOS and it's worked fantastically, but I've not found where/how to do this on the Nexus 7010 platform (or any Nexus platform) as of yet. I could have sworn that this was going to be introduced in the 6.x code? Below is an example of how we do this in the IOS world:
track 11 ip sla 1 reachability
delay down 15 up 15
ip sla 1
[Code]....
Esentially this gives us the option of using a "failover" default route. I've attached a basic diagram to explain what we are trying to do with IP SLAs and object checking. The tracking should be configured against an SLA that uses icmp and the static routes should be configured against the tracking.
IP SLA configuration fails over but cannot ping the 4.2.2.2 via Site B. Here is the output on Cisco 3750...

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.
Since the ACE supports only static routing, when pointing a default route from the ACE what is your preferred method when using multiple 6500s with an ACE in each in a failover scenario to prevent just pointing at one 6500? Static route to an HSRP address? Multiple static routes on the ACE, etc?

I just got my Cisco SG300 28, but I have some problems getting the routing to work. I get the vlans to get to the router, with the default route. But not getting them to talk with each other. I can ping the IPs from the cisco, but I am not getting traffic to go from vlan 1 to vlan 2. When I try to google, it say that it should do it automatically, and I found no setting for it. It looks like it not creating any route for the interfaces.

We have recently purchased a Cisco SG300 and have been configuring it. [code] The VLANs have ACLs set up to prevent any communication between the Holly and Tempo VLANs (and their associated WAN VLANs).Each VLAN has a WAN available for it's use, which connects to external networks (including the Internet).In order to facilitate this, we have set up all the necessary ACLs and routes and confirmed that this all works.However, the problem comes when we assign the static routes that specify the default gateways.We add the two static routes below:
-0.0.0.0 next hop 10.10.200.254 metric 1
-0.0.0.0 next hop 192.168.200.254 metric 1
In this case, only one of the VLANs has WAN access. It is either Holly or Tempo (it can be either if the order the static route is added is changed).What we need is to force Holly to use Holly WAN and Tempo to use Tempo WAN, but we cannot see a way of doing this.Effectively, we want the following static routes: [code]
Right now I have 2 default routes load balancing 100MB internet links. This is on my 2 6509's.

ip route 0.0.0.0 0.0.0.0 10.47.2.250 (5510)

Have a 1921 that has 3 eth connections (1 LAN, and 2 WAN) - I have 2 seperate OSPF processes (2 areas) on the WAN Ints - both upstream WAN's are sending defaults back to the 1921, and the 1921 is sending it's LAN range to them.
I have ip ospf cost 150 set on the "failover" WAN connection interface (Both on the 1921 and upstream), but the 1921 is preferring the default route from the "failover"?
The default routes are both being received by the 1921, but it's preferring the "failover" Int with the ip ospf cost 150 configured?
Recently we observed that newly installed WS-C3560CG-8PC access switches are able to communicate without a default route or default gateway.The 3650 switches are used as a layer2 access switch behind a layer3 distribution/core. They have only the management VLAN configured for IP with a single address.
The ARP table looks like there is an implicit proxy-ARP request sent for any IP address.
We definitely have no configuration whatsoever which would explain this.
Is this a new feature? We don't observe that with the older 2960-series...

The mac address if of course the mac address of the layer 3 interfaces of the distribution switch, no surprise here (proxy ARP is turned on by default).
Why is the 3560 sending out proxy arp requests without being told to? As far as I understood proxy ARP on Cisco IOS it only means it will reply to a proxy ARP request but will not send out proxy ARP requests by default.
I've got two Nexus 7010's running HSRP north bound to a pair of ASA's, and BGP south bound to four 6509's. Is it possible to advertise default route to BGP neighbor (or prefer it via MED), only if the node is HSRP-active?
Essentially the goal is to create symmetry for inbound/outbound traffic. Only way I can think of so far is via an EEM script, so that when it sees HSRP go active via syslog, it would kick off an action to remove ASN prepend, or reduce MED, and the opposite if HSRP goes standby.
I have a question about filtering incoming bgp route updates from an internet provider. This provider sends the full internet routing table and default route and on an incoming prefix-filter on the customer switch (C6509-sup720) the default route is only accepted.What happens on the 6509 switch when the BGP peer flaps?Does it need to process all the internet routing updates, and if yes probably it cannot handle all these updates?What happens with the CEF table, will the switch install the routes first?

A check out a network segment and want to know why SwA has a static route to SwB if SwA already has a Default GW to Core?
(SwA, SwB - Catalyst3560, Core - Catalyst4948)Note, there are distribute list on SwA - it does not has any OSPF route (exclude O*IA).
Does this mean when SwA send out packet with DA 10.5.64.0/26, Core will use only L2 switching (instead of L3)? Is this more effectively for Core Switch?
Pleace check my reasoning:
1. When use a static route: SwA receive packet from Vlan 20 with DA 10.5.64.0/26 it will strip out Dest. MAC and replace it with MAC of SwB. Core will switch this packet to SwB based on mac add. table (l2 switching)
2. When SwA has only Default gateway and receive packet from Vlan20 with DA 10.5.64.0/26 it replace Dest. MAC with Core MAC. Core receive this packet, lookup route table for 10.5.64.0 entry and forward packet base on this.
