PBR next-hop and default next-hop
When implementing Policy Based Routing, the
set ip default next-hop and the
set ip next-hop commands perform two different functions. These are described in detail below:
set ip default next-hop command verifies the existence of the destination IP address in the routing table, and…
- if the destination IP address exists, the command does not policy route the packet, but forwards the packet based on the routing table.
- if the destination IP address does not exist, the command policy routes the packet by sending it to the specified next hop.
set ip next-hop command verifies the existence of the next hop specified, and…
- if the next hop exists in the routing table, then the command policy routes the packet to the next hop.
- if the next hop does not exist in the routing table, the command uses the normal routing table to forward the packet.
