Subject: zebra: Allow vrfs to be defined and displayed before netlink vrf add
X-Git-Tag: frr-2.0-rc1~942
X-Git-Url: https://git.puffer.fish/?a=commitdiff_plain;h=825649bd9fc0d44014ddd81bd460ec1f83270884;p=matthieu%2Ffrr.git

zebra: Allow vrfs to be defined and displayed before netlink vrf add

Displays vrfs using the vrf_list rather than the route-nodes.  This allows "show vrf"
to display inactive (or not yet active) vrfs.  Also, IPv6 static routes are now
allowed to be defined and displayed prior to the netlink vrf add.
