IS-IS Commands
18-15
isis priority
A BSR uses hello packets to advertise its priority to become a designated router. IS-IS
uses the advertised priorities on all multiaccess networks to elect a designated router
for the network. This router is responsible for sending network LSP advertisements,
which describe all the routers attached to the network. These advertisements are
flooded throughout a single area. The priority value is meaningful only on a
multiaccess network. It has no meaning on a point-to-point interface.
A router’s priority for becoming the designated router is indicated by an arbitrary
number. Routers with a higher value are more likely to become the designated router.
By default, routers have a priority value of 64.
The isis priority command is used to select the designated router priority.
