snmp-server community vrf2 ro
snmp-server context context1
snmp-server context context2
snmp mib community-map vrf1 context context1
snmp mib community-map vrf1 context context2
2. Configure snmp context under the VRF instances.
sho run bgp
router bgp 100

snmp context context1
neighbor 20.1.1.1 remote-as 200
neighbor 20.1.1.1 no shutdown
