时间值:
P2P | HELLO 10 | DEAD 30 |
DIS | HELLO 3 | DEAD 10 |
非DIS | HELLO 10 | DEAD 30 |
广播型链路DIS选举出来后,3s发一次hello。
命令:
int g0/0/0
isis timer hello 3 level-2 //设置级别2的hello每隔3s发送一次,点到点链路无需加级别
isis timer hold-multipter 4 level-2 //设置holdtimer时间是hello时间的几倍

注意:
1、ISIS的邻居关系建立hello和hold时间不一致,不影响邻居关系的建立;
2、hold timer时间默认是hello时间的三倍,hello默认每隔10s发一次,是告知邻居本端失效时间;
