VRF - Virtual Route Forwarding

It creates a virtual routing table and routing of traffic, coming on interfaces which are part of that vrf, will be done through that virtual routing table

It is having two components

RD - Route Distinguisher

RT - Route Target

RD acts as route distinguisher on RR for overlapping subnets for different customers. RD local to the router and should be unique on that router. Same RD can not be assigned to two VRFs on same router.

RT is extended community. You can export multiple RT along with vpnv4 BGP updates. Based on RT

remote side router can accept interested prefixes with RT import on that vrf.

RD is part of the prefix while RT travels as extended community.
