vrf route targets - how to import vrf routes into each other

[carl_townshend]

Hi All

im trying to look at some GNS 3 vrf labs

If i have 2 vrf's on a router, and I run eigrp process on them,

How do I get the routes from 1 vrf into the other?

do I need to do the import and export and also redistribute eigrp ?

please help

You have to import the routes that you're exporting from the other vrf. In a nutshell you'd need bgp vpnv4 to carry your eigrp routes across the lsp. You run eigrp and bgp on both PEs and you redistribute between these two protocols using address-families. To create the vrfs, you'd have a route distinguisher and route-targets that import and export the same target.

ip vrf CustA

rd 100:100

route-target both 100:100

just to ad to the other posts

the RT is used for import and export also used for route leaking between VRFs

if you are using VRF lite with no MPLS then you will need a local BGP instance so that you can use the vrf address-family for the import and and export between the two VRFs

if you want if the import and export to be selectively not every thing you can use a route-map in this case see the below links for more details
