Example:
RP/0/RP0/CPU0:router(config-mpls-static)# vrf vrf1 address-family ipv4 unicast
Applies the static configuration to an IPv4 address family in the VRF named vrf1.
Step 4
local-label label-value allocate per-prefix IPv4_prefix_entry
•
•
local-label label-value allocate per-vrf forward path path-id pop-and-lookup
Example:
RP/0/RP0/CPU0:router(config-mpls-static-vrf-af)# local-label 30500 allocate per-prefix 100.1.1.0/24
The MPLS protocol requests label 30500 to be statically bound as a local label for the prefix 100.1.1.0/24 in the VRF
named vrf1.
Example:
RP/0/RP0/CPU0:router(config-mpls-static-vrf-af)# local-label 30500 allocate per-vrf forward path 1
pop-and-lookup
The MPLS protocol requests single label 30500 to be statically bound as a local label for all the prefixes in the VRF
named vrf1. When the router receives packets with VRF label 30500, it removes the label and then performs IP-based
lookup to forward the packets.
Step 5
Use the commit or end command.
commit—Saves the configuration changes and remains within the configuration session.
end—Prompts user to take one of these actions:
• Yes— Saves configuration changes and exits the configuration session.
• No—Exits the configuration session without committing the configuration changes.
• Cancel—Remains in the configuration session, without committing the configuration changes.
