Import EIGRP default route only with network command

Hi,

Does anyone know why I can only import the default route learned by EIGRP (from a CE router) in the VPNV4 table with the command ?network 0.0.0.0? under the address family? Is this the correct behavior?

router bgp 100

address-family ipv4 vrf red

redistribute eigrp 200

no synchronization

network 0.0.0.0

exit-address-family

PE9(config-router-af)#do show ip route vrf red 0.0.0.0

Hi Marcelo,

Yes this is normal, a default route unlike any other routes is not redistributed between routing protocols by default, in the case of BGP you have 2 options, either use a network command and make sure that the route is in the routing table (via EIGRP in your case), or use redistribute + default-information originate, you can test this by removing the network command and adding the default-information originate under the address family.
