Configuring IP Unicast Routing
Configuring Multi-VRF CE
The following example shows how to send all SNMP notifications to example.com over the VRF named trap-vrf using the
community string public:
Switch(config)# snmp-server host example.com vrf trap-vrf public
User Interface for HSRP
Hot Standby Router Protocol (HSRP) support for VRFs ensures that HSRP virtual IP addresses are added to the correct
IP routing table.

Configure a VRF as described in the Configuring VRFs, page 897.
DETAILED STEPS
EXAMPLE
Switch(config)# interface ethernet 0
Switch(config-if)# no switchport
Switch(config-if)# ip vrf forwarding vpn1
Switch(config-if)# ip address 172.16.1.3
