Command Remarks
3. Specify an IS-IS cost style.
cost-style { wide |
wide-compatible }
By default, the IS-IS cost style is
narrow.
4. Enter IPv6 address family view.
address-family ipv6 [ unicast ] N/A
5. Enable IPv6 IS-IS MTR.
multi-topology [ compatible ]
By default, IPv6 IS-IS MTR is
disabled.
6. Assign a convergence priority
to specific IPv6 IS-IS routes.
• prefix-priority { critical | high |
medium } { prefix-list
prefix-list-name | tag
tag-value }
• prefix-priority route-policy
route-policy-name
Use either command.
By default, IPv6 IS-IS routes, except
IPv6 IS-IS host routes, have the low
convergence priority.
Setting the LSDB overload bit

Command Remarks
1. Enter system view.
system-view N/A
2. Enter IS-IS view.
isis [ process-id ] [ vpn-instance
vpn-instance-name ]
N/A
3. Specify an IS-IS cost style.
cost-style { wide |
wide-compatible }
By default, the IS-IS cost style is
narrow.
4. Enter IPv6 address family view.
address-family ipv6 [ unicast ] N/A
5. Enable IPv6 IS-IS MTR.
multi-topology [ compatible ]
By default, IPv6 IS-IS MTR is
disabled.
6. Set the overload bit.
set-overload [ on-startup
[ [ start-from-nbr system-id
[ timeout1 [ nbr-timeout ] ] ] |
timeout2 ] [ allow { external |
interlevel } * ]
By default, the overload bit is not
set.
Configuring a tag value on an interface
Perform this task when the link cost style is wide, wide-compatible, or compatible.
When IS-IS advertises a prefix with a tag value, IS-IS adds the tag to the IP reachability information TLV
of the prefix.
To configure a tag value on an interface:

Command Remarks
1. Enter system view.
system-view N/A
2. Enter interface view.
interface interface-type
interface-number
N/A
3. Configure a tag value on the
interface.
isis ipv6 tag tag
By default, no tag value is
configured on an interface.
