我正在尝试为具有以下配置的网络设置基本的 ISIS 路由策略：
服务器 A：
router1.home.domain1.net# show running-config
Current configuration:
!
hostname router1.domain1.net
password abcdefg
!
interface he-wan0
!
interface lan0
!
interface lo
!
interface serverconn
ip router isis interconnections
isis circuit-type level-1-2
isis hello-interval 5
isis priority 1
!
interface wan0
!
interface wlp2s0
!
router isis interconnections
net 49.2112.4120.2420.0000.00
metric-style narrow
!
line vty
!
end
服务器B：
server0.domain2.com(config-if)# show running-config
Current configuration:
!
password abcdefg2
!
interface domain1connect
ip router isis interconnections
isis circuit-type level-1-2
isis hello-interval 5
isis priority 10
!
interface eno1
!
interface eno2
!
interface ens3f0
!
interface ens3f1
!
interface lo
!
interface userlan
!
router isis interconnections
net 49.2113.1872.1900.0000.00
metric-style narrow
!
line vty
!
end
目前，我可以看到来自 domain1.net 的流量（通过 tcpdump）：

我似乎无法弄清楚为什么这两个路由器无法互相看到，如能得到任何帮助我将非常感谢。
我已经尝试使用相同的区域 ID 并将其设置为 1 级连接，但这似乎也不起作用。
谢谢。
