inter-as-hybrid
To specify a VRF as an Option AB VRF, use the inter-as-hybrid command. Routes imported to this VRF
can be advertised to Option AB peers and VPNv4 iBGP peers. When routes are received from Option
AB peers and imported into the VRF, the next-hop tableid of the route is set to the tableid of the VRF.

Command History
Usage Guidelines The following usage guidelines apply to the cs
c keyword:
• If the csc keyword is not used, a per-VRF label is allocated for imported routes.
• When routes are received from Option AB peers and are imported next into the VRF, the learned out
label can only be installed in forwarding when the csc keyword is used.
• For routes received from Option AB peers that are imported into the VRF, the learned outlabel is
installed in forwarding.
Examples The following example specifies a VRF as an Option AB VRF:
Router(config-vrf-af)# inter-as-hybrid
csc (Optional) If the csc keyword is used, then a per-prefix label is allocated for
imported routes. For routes received from Option AB peers that are imported
into the VRF, the learned outlabel is installed in forwarding.
next-hop (Optional) Specifies the next-hop IP address to be set on paths that are
imp
orted into the VRF and that are received from an Option AB peer. The
next-hop context is also set to the VRF, which imports these paths. If the
next-hop keyword is not used, the received next-hop is retained but the
next-hop context (for paths received from Option AB peers) is still set to that
of the VRF.
ip-address Specifies the IP address of the Inter-AS AB neighbor.
