PBR in VLT Domain

Policy-based routing (PBR) provides a mechanism to redirect IPv4 and IPv6 data packets based on the policies defined to override the forwarding decisions of the switch based on the routing table. These packets can be routed to alternate destination or dropped based on the policies defined. PBR is enabled at ingress direction of Layer 3 interface. PBR is configured using policy route map with specific matching condition and action to be taken. When you configure PBR in a VLT setup, configure the same PBR rules on both VLT peers. For more information about PBR, see Policy-based routing.

Use the [no] ip pbr disable and [no] ipv6 pbr disable commands to disable or re-enable IPv4 PBR and IPv6 PBR on VLT domain, respectively. Use the show vlt domain-id pbr to view the PBR configuration status on VLT domain.

The following example shows PBR configuration on the VLT peers.
