Examples
The following example shows how to configure an IPv4 VRF address family session after defining the VRF named vrf1:
Routing(config)# router eigrp 1
Routing(config-eigrp)# vrf vrf1
Routing(config-eigrp-vrf)# address-family ipv4
Routing(config-eigrp-vrf-af)# default-metric 1000 100 255 1 1500
