Configuring system ID to host name mappings
A 6-byte system ID in dotted decimal notation uniquely identifies a router or host uniquely. This format
makes system IDs not straightforward. To solve the issue, the system allows you to use host names to
identify devices and provides mappings between system IDs and host names.
The mappings can be configured manually or dynamically. Follow these guidelines when you configure
the mappings:
• To view host names rather than system IDs by using the display isis lsdb command, you must enable
dynamic system ID to host name mapping.
• If you configure both dynamic mapping and static mapping on a router, the host name specified for
dynamic mapping applies.
Configuring a static system ID to host name mapping
Ste

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. Configure a system ID to host
name mapping for a remote IS.
is-name map sys-id
map-sys-name
A system ID can only correspond to
a host name.
Configuring dynamic system ID to host name mapping
Static system ID to host name mapping requires you to manually configure a mapping for each router in
a network. When a new router is added into the network or a mapping must be modified, you must
configure all routers manually.
Dynamic system ID to host name mapping can solve the problem. You only need to configure a host
name for each router in the network. Each router advertises the host name in a dynamic host name CLV
to other routers so all routers in the network then have all the mappings.
To help check the origin of LSPs in the LSDB, you can configure a name for the DIS in a broadcast
network.
