DETAILED STEPS
Step 1
configure
Step 2
router isis instance-id
Example:
RP/0/RP0/CPU0:router(config)# router isis isp
Enables IS-IS routing for the specified routing process, and places the router in router configuration mode.
• By default, all IS-IS instances are automatically Level 1 and Level 2. You can change the level of routing to be
performed by a particular routing instance by using the is-type command.
Step 3
set-overload-bit [ on-startup { delay | wait-for-bgp }] [ level { 1 | 2 }]
Example:

configure
router isis instance-id
set-overload-bit [ on-startup { delay | wait-for-bgp }] [ level { 1 | 2 }]
address-family { ipv4 | ipv6 } [ unicast ]
default-information originate [ route-policy route-policy-name ]
distribute-list { {prefix-list prefix-list-name | route-policy route-policy-name}
redistribute isis instance [ level-1 | level-2 | level-1-2 ] [ metric metric ] [ metric-type { internal
| external }] [ policy policy-name ]
Do one of the following:
• summary-prefix address / prefix-length [ level { 1 | 2 }]
• summary-prefix ipv6-prefix / prefix-length [ level { 1 | 2 }]
maximum-paths route-number
distance weight [ address / prefix-length [ route-list-name ]]
set-attached-bit
