    Default BGP VRF Redistribution Question

    Refer to the config below:

    R2(config)#router bgp 100
    (config-router)#address-family ipv4 vrf A
    (config-router-af)#redistribute static
    (config-router-af)#network 10.1.2.0 mask 255.255.255.0

    R2# sh bgp vpnv4 unicast all

    How come the static route and 10.1.2.0/24 are inside the vpnv4 address family?
    I thought I only redistribute it into BGP?
    How does BGP know that it has to place it in the VPNv4 address family?
    I mean, there are so many protocols running in BGP. How does BGP know what to do with it?

    When you create the "address-family ipv4 vrf A" you're telling BGP this is an instance within the VRF. VRF routes are carried using VPNv4.
    An expert is a man who has made all the mistakes which can be made.
