5. Enable IPv6 IS-IS MTR.
multi-topology

By default, IPv6 IS-IS MTR is
disabled.
6. Assign a convergence
priority to specific IPv6 IS-IS
routes.
• Method 1:
prefix-priority { critical |
high | medium } { prefix-list
prefix-list-name | tag
tag-value }
• Method 2:
prefix-priority route-policy
route-policy-name
By default, IPv6 IS-IS routes,
except IPv6 IS-IS host routes,
have the low convergence priority.

Configuring a tag value on an interface
When IS-IS advertises an IPv6 prefix with a tag value, it adds the tag to the IPv6 reachability
information TLV, regardless of the link cost style.
