Tagging Routes: Example
The following example shows how to tag routes.
route-policy isis-tag-55
end-policy
!
route-policy isis-tag-555
if destination in (5.5.5.0/24 eq 24) then
set tag 555
pass
else
drop
endif

Configuring IS-IS Overload Bit Avoidance: Example
The following example shows how to activate IS-IS overload bit avoidance:
config
mpls traffic-eng path-selection ignore overload
The following example shows how to deactivate IS-IS overload bit avoidance:
config
no mpls traffic-eng path-selection ignore overload
Example: Configuring IS-IS To Handle Router Overload
This section describes an example for configuring IS-IS to handle overloading of routers, without setting the
overload bit.
When a router is configured with the IS-IS overload bit, it participates in the routing process when the overload
bit is set, but does not forward traffic (except for traffic to directly connected interfaces). To configure the
overload behavior for IS-IS, without setting the overload bit, configure the max-link-metric statement. By
