Implementing VRF

To configure a VRF:

• Create the VRF in any command mode, optionally specifying an SNMPv3 context name.
• Enter the VRF router mode, followed by entering configuration mode for the created VRF.
• On the S- and K-Series, for each VRF with a subnet reachable by a different VRF instance, configure static routes to perform next hop lookup in the VRF instance.
• On the S- and K-Series, for IP address policy, in which the next hop interface is a member of a different VRF, when configuring a policy route map, set the next hop behavior to perform the route lookup on the next hop VRF.
• On the S-Series, when multiple VRFs contain overlapping IP networks that communicate to a larger Internet, use the NAT-inside-VRF feature to differentiate between the VRFs containing the overlapping IP networks.
• On the S-Series, when a single VRF provides Server Load Balancing (SLB) services for multiple VRFs, configure the virtual server to provide SLB services to all VRFs in this router.
• On the S- and K-Series, when changing the destination address for the forwarding of local UDP broadcasts to an address located on a different VRF, specify the destination VRF in the helper address configuration. Also, set DHCP relay information to force the client to include VPN option 82 in packets sent to the DHCP server.
