DETAILED STEPS
PurposeCommand or Action
configure
Step 1
Enters interface configuration mode and associates
one or more interfaces to the VRF.
interface type interface-path-id
Example:
RP/0/RSP0/CPU0:router(config-if)# interface
GigabitEthernet 0/0/0/0
Step 2
Enables flow-tag policy propagation on source or
destination IP address on an interface.
ipv4 | ipv6 bgp policy propagation input
flow-tag{destination |source}
Example:
RP/0/RSP0/CPU0:router(config-if)# ipv4 bgp policy
propagation input flow-tag source
Step 3
commit
Step 4
The following show commands display outputs with PBR policy applied on the router:
show running-config interface gigabitEthernet 0/0/0/12
