Usage
Information
You can apply any number of redirect-groups to an interface. A redirect list can contain any number
of configured rules. These rules includes the next-hop IP address where the incoming traffic is to be
redirected.
If the next hop address is reachable, traffic is forwarded to the specified next hop. Otherwise, the normal
routing table is used to forward traffic. When a redirect-group is applied to an interface and the next-hop
is reachable, the rules are added into the PBR CAM region. When incoming traffic hits an entry in the
CAM, the traffic is redirected to the corresponding next-hop IP address specified in the rule.
NOTE: Apply the redirect list to physical, VLAN, or LAG interfaces only.
The Layer2 PBR option matches the layer2 traffic flow. If you un-configure this option, then the Layer2
traffic is not matched. You can apply the l2–switch option to redirect Layer2 traffic only on a VLAN
interface. This VLAN interface must be configured with an IP address for ARP resolution.
NOTE: The l2–switch option that redirects Layer2 traffic is applicable only on VLAN interfaces.
The Layer3 routing is not affected on the same interface on which Layer2 PBR is applied. The port from
which Layer2 packets egress and the destination MAC are re-written from static ARP. Layer 2 packets
with the re-written destination MAC are forwarded through the outgoing port on the same incoming
VLAN interface. The layer2-switch option ensures that the outgoing VLAN and MAC-SA are changed and
TTL is not decremented.
