Advertising multiple default routes with EIGRP

Advertising multiple default routes with EIGRP open original image

It seems like my default route advertisements are being stopped at the MPLS edge routers of my service provider. I am running EIGRP across these routers already and everything else is propagating normally. Here is the pertinent info from the config on one router:



router eigrp 1 redistribute connected redistribute static ! - passives omitted network 10.1.0.0 0.0.255.255 network 10.10.0.0 0.0.255.255 network 10.11.0.0 0.0.255.255 network 10.12.0.0 0.0.255.255 network 10.16.0.0 0.0.255.255 network 172.20.148.88 0.0.0.3 network 0.0.0.0 default-metric 10000 1 255 1 1500 no auto-summary ! ip classless ip default-network 0.0.0.0 ip route 0.0.0.0 0.0.0.0 10.10.100.2



I have local Internet connections at each facility that connects across the MPLS so it makes sense to leverage those multiple connections to create some redundancy for Internet access. Am I going about this the wrong way?



Any help is appreciated, Steve



Your need to discuss the issue with default not being carried across the MPLS cloud with you service provider.

Meanwhile you can implement backup default routing at each of your remote sites by using "Reliable Static Routing Backup Using Object Tracking".

I take it the PE router is on another interface and that 10.10.100.2 is a default route out to a non-MPLS service provider?

Do you need the "network 0.0.0.0" command (as well as the others). Not sure what that is meant to do. If all of your interfaces are selected by network statements I'm not sure that "redistribute connected" has value. I don't think you need "ip default-network 0.0.0.0" since as long as the router has the ip route to 0.0.0.0 EIGRP should advertise that as a default. . FYI there is an option: passive-interface default which means that you can run no passive-interface to explicitly specify which interfaces are to run the routing protocol.
