R0106-HP MSR Router Series Layer 3 - IP Routing Command Reference(V7)

283
When network changes are not frequent, the minimum-interval is adopted. If network changes become
frequent, the SPF calculation interval is incremented by the incremental-interval each time a generation
happens until the maximum-interval is reached.
The minimum interval and the incremental interval cannot be greater than the maximum interval.
Examples
# Configure the maximum interval as 10 seconds, the minimum interval as 100 milliseconds, and the
incremental interval as 300 milliseconds.
<Sysname> system-view
[Sysname] isis 1
[Sysname-isis-1] timer spf 10 100 300
topology
Use topology to create an IS-IS IPv4 unicast topology and enter its view.
Use undo topology to remove all configurations in the view.
Syntax
topology topo-name [ tid tid ]
undo topology topo-name
Default
IS-IS IPv4 unicast topology is not created.
Views
IS-IS IPv4 unicast address family view
Predefined user roles
network-admin
Parameters
topo-name: Specifies a topology by its name, a case-sensitive string of 1 to 31 characters.
tid: Specifies the topology number in the range of 6 to 4095.
Usage guidelines
The name base is reserved for the base topology.
This command takes effect after the related IPv4 subtopology is configured.
This command can be configured only when the link cost style is wide, compatible, or wide-compatible.
Examples
# Create IS-IS IPv4 unicast topology voice (4000) and enter its view.
<Sysname> system-view
[Sysname] isis 100
[Sysname-isis-100] address-family ipv4
[Sysname-isis-100-ipv4] topology voice tid 4000
[Sysname-isis-100-ipv4-topo-voice]
