RP/0/RP0/CPU0:router(config-isis)# set-overload-bit

(Optional) Sets the overload bit.

The configured overload bit behavior does not apply to NSF restarts because the NSF restart does not set the

overload bit during restart.

Note

Step 4 address-family { ipv4 | ipv6 } [ unicast ]

Example:

RP/0/RP0/CPU0:router(config-isis)# address-family ipv4 unicast

Specifies the IPv4 or IPv6 address family, and enters router address family configuration mode.

Step 5 default-information originate [ route-policy route-policy-name ]

Example:

RP/0/RP0/CPU0:router(config-isis-af)# default-information originate

(Optional) Injects a default IPv4 or IPv6 route into an IS-IS routing domain.

• The route-policy keyword and route-policy-name argument specify the conditions under which the IPv4 or

IPv6 default route is advertised.

• If the route-policy keyword is omitted, then the IPv4 or IPv6 default route is unconditionally advertised at Level

Step 6 distribute-list { {prefix-list prefix-list-name | route-policy route-policy-name} } in

Example:

RP/0/RSP0/CPU0:router(config-isis)# distribute-list { {prefix-list | prefix-list-name} |

{route-policy | route-policy-name} } in

(Optional) Filters the routes that Intermediate System-to-Intermediate System (IS-IS) installs in the Routing Information

Base (RIB).

When distribute-list in command is configured, some routes that IS-IS computes are not installed in the

forwarding plane of the local router, but other IS-IS routers will not be aware of this. This introduces a

difference between the forwarding state computed by other IS-IS routers and the actual forwarding state on

this router. In some cases, this could lead to traffic being dropped or looped. Hence, be careful about when

to use this command.

Warning

Step 7 redistribute isis instance [ level-1 | level-2 | level-1-2 ] [ metric metric ] [ metric-type { internal | external

}] [ policy policy-name ]

Example:

RP/0/RP0/CPU0:router(config-isis-af)# redistribute isis 2 level-1

(Optional) Redistributes routes from one IS-IS instance into another instance.

• In this example, an IS-IS instance redistributes Level 1 routes from another IS-IS instance.
