Administrator Guide
To map the context to a VRF instance for SNMPv3, follow these steps:
1. Create a community and map a VRF to it. Create a context and map the context and community, to a community map.
• snmp-server community public ro
• snmp-server community VRF1 ro
• snmp-server community VRF2 ro
• snmp-server context cx1
• snmp-server context cx2
• snmp-server group admingroup 3 auth read readview write writeview
• snmp-server group admingroup 3 auth read readview context cx1
• snmp-server group admingroup 3 auth read readview context cx2
• snmp-server user admin admingroup 3 auth md5 helloworld
• snmp mib community-map VRF1 context cx1
• snmp mib community-map VRF2 context cx2
• snmp-server view readview .1 included
• snmp-server view writeview .1 included
2. Configure snmp context under the VRF instances.
• sho run bgp
• router bgp 100
• address-family ipv4 vrf vrf1
• snmp context context1
• neighbor 20.1.1.1 remote-as 200
• neighbor 20.1.1.1 no shutdown
• exit-address-family
• address-family ipv4 vrf vrf2
• snmp context context2
• timers bgp 30 90
• neighbor 30.1.1.1 remote-as 200
• neighbor 30.1.1.1 no shutdown
• exit-address-family
