Match routes
Congure match criterion for a route-map. There is no limit to the number of match commands per route map, but keep the number of
match lters in a route-map low. The
set commands do not require a corresponding match command.
• Match routes with a specic metric value in ROUTE-MAP mode (0 to 4294967295).
match metric metric-value
• Match routes with a specic tag in ROUTE-MAP mode (0 to 4294967295).
match tag tag-value
• Match routes whose next hop is a specic interface in ROUTE-MAP mode.

• ethernet — Enter the Ethernet interface information.
• port-channel — Enter the port-channel number.
• vlan — Enter the VLAN ID number.

OS10(config)# route-map test permit 1
0S10(conf-route-map)# match tag 250000
OS10(conf-route-map)# set weight 100
OS10(conf-route-map)# do commit
