Examples
This example shows how to configure object tracking for detecting access connectivity for the specific SRG
in MC-LAG scenario:
Configuring the track object:
RP/0/RSP0/CPU0:router# configure
RP/0/RSP0/CPU0:router(config)# track mclag-be1
RP/0/RSP0/CPU0:router(config-track)# type line-protocol state
RP/0/RSP0/CPU0:router(config-track-line-prot)# interface Bundle-Ether1
Configuring that track object under the SRG which holds that particular interface:
RP/0/RSP0/CPU0:router# configure
RP/0/RSP0/CPU0:router(config)# subscriber redundancy
RP/0/RSP0/CPU0:router(config-subscr-red)# group 1
RP/0/RSP0/CPU0:router(config-subscr-red-group)# access-tracking mc-lag-be1
Configuring access-tracking - Routing:
router static
address-family ipv4 unicast
200.0.0.0/16 Null0 track mc-lag-be1
address-family ipv6 unicast
20::/64 Null0 track mc-lag-be1
router isis 1
address-family ipv4 unicast
redistribute static
address-family ipv6 unicast
