MPLS-BGP Support on the Service Side

This features allows you to enable support on Multiprotocol Label Switching (MPLS). Multiple Service VPNs use inter autonomous system (AS) BGP labelled path to forward the traffic, which in turn helps scaling the service side VPNs with less control plane signaling.

Label distribution for a given VPN routing and forwarding (VRF) instance on a given device can be handled by Border Gateway Protocol (BGP).

BGP Community Propagation

Cisco IOS XE Catalyst SD-WAN Release 17.3.1a

Cisco vManage Release 20.3.1

This feature enables propagation of BGP communities between routing protocols during route redistribution. On one node, the OMP redistributes routes from BGP and on the other node, the BGP redistributes routes from OMP. In addition to configurable AS path attribute propagation, there is an option to propagate BGP communities. The BGP community propagation helps in propagating BGP communities between Cisco Catalyst SD-WAN sites, across VPNs using OMP redistribution. To propagate the BGP communities during route redestribution from OMP, use the propagate-community command.

Ability to Match and Set Communities during BGP to OMP Redistribution

Cisco vManage Release 20.4.1

This feature enhances the implementation of match and set clauses for redistribution of routes from BGP to OMP and vice versa on Cisco IOS XE Catalyst SD-WAN devices. You can redistribute the routes from a BGP into an OMP routing to allow route traffic to help increase the accessibility within the network. The route-maps are defined locally on each device to filter the routes from the source routing protocol. You can manipulate OMP communities to propagate BGP routes. The following commands are updated:

route-map

advertise bgp route-map bgp-to-omp

redistribute omp route-map omp-to-bgp
