R3:3.3.3.3
R4:4.4.4.4
測試目的:
ISIS的互接測試
Lab:
1. 先把互聯的界面都設定完成:
set logical-systems r1 interfaces em1 unit 12 vlan-id 12
set logical-systems r1 interfaces em1 unit 12 family inet address 192.168.12.1/30
set logical-systems r1 interfaces em1 unit 12 family iso
set logical-systems r1 interfaces em1 unit 13 vlan-id 13
set logical-systems r1 interfaces em1 unit 13 family inet address 192.168.13.1/30
set logical-systems r1 interfaces em1 unit 13 family iso
set logical-systems r1 interfaces em1 unit 14 vlan-id 14
set logical-systems r1 interfaces em1 unit 14 family inet address 192.168.14.1/30
set logical-systems r1 interfaces em1 unit 14 family iso
set logical-systems r1 interfaces lo0 unit 1 family inet address 1.1.1.1/32
set logical-systems r2 interfaces em1 unit 23 vlan-id 23
set logical-systems r2 interfaces em1 unit 23 family inet address 192.168.23.1/30
set logical-systems r2 interfaces em1 unit 23 family iso
set logical-systems r2 interfaces em1 unit 24 vlan-id 24
set logical-systems r2 interfaces em1 unit 24 family inet address 192.168.24.1/30
set logical-systems r2 interfaces em1 unit 24 family iso
set logical-systems r2 interfaces em2 unit 12 vlan-id 12
set logical-systems r2 interfaces em2 unit 12 family inet address 192.168.12.2/30
set logical-systems r2 interfaces em2 unit 12 family iso
set logical-systems r2 interfaces lo0 unit 2 family inet address 2.2.2.2/32
set logical-systems r3 interfaces em1 unit 34 vlan-id 34
set logical-systems r3 interfaces em1 unit 34 family inet address 192.168.34.1/30
set logical-systems r3 interfaces em1 unit 34 family iso
set logical-systems r3 interfaces em2 unit 13 vlan-id 13
set logical-systems r3 interfaces em2 unit 13 family inet address 192.168.13.2/30
set logical-systems r3 interfaces em2 unit 13 family iso
set logical-systems r3 interfaces em2 unit 23 vlan-id 23
set logical-systems r3 interfaces em2 unit 23 family inet address 192.168.23.2/30
set logical-systems r3 interfaces em2 unit 23 family iso
set logical-systems r3 interfaces lo0 unit 3 family inet address 3.3.3.3/32
set logical-systems r4 interfaces em2 unit 14 vlan-id 14
set logical-systems r4 interfaces em2 unit 14 family inet address 192.168.14.2/30
set logical-systems r4 interfaces em2 unit 14 family iso
set logical-systems r4 interfaces em2 unit 24 vlan-id 24
set logical-systems r4 interfaces em2 unit 24 family inet address 192.168.24.2/30
set logical-systems r4 interfaces em2 unit 24 family iso
set logical-systems r4 interfaces em2 unit 34 vlan-id 34
set logical-systems r4 interfaces em2 unit 34 family inet address 192.168.34.2/30
set logical-systems r4 interfaces em2 unit 34 family iso
set logical-systems r4 interfaces lo0 unit 4 family inet address 4.4.4.4/32
確定是否設定成功，以ping的方式去確認
2. 設定ISIS相關設定:
interface加入family iso跟在loopback加入NET位址[network entity title (NET)]
set logical-systems r1 interfaces em1 unit 12 family iso
set logical-systems r1 interfaces em1 unit 13 family iso
set logical-systems r1 interfaces em1 unit 14 family iso
set logical-systems r1 interfaces lo0 unit 1 family iso address 49.0001.0001.0001.0001.00
set logical-systems r2 interfaces em1 unit 23 family iso
set logical-systems r2 interfaces em1 unit 24 family iso
set logical-systems r2 interfaces em2 unit 12 family iso
set logical-systems r2 interfaces lo0 unit 2 family iso address 49.0001.0002.0002.0002.00
set logical-systems r3 interfaces em1 unit 34 family iso
set logical-systems r3 interfaces em2 unit 13 family iso
set logical-systems r3 interfaces em2 unit 23 family iso
set logical-systems r3 interfaces lo0 unit 3 family iso address 49.0001.0003.0003.0003.00
set logical-systems r4 interfaces em2 unit 14 family iso
set logical-systems r4 interfaces em2 unit 24 family iso
set logical-systems r4 interfaces em2 unit 34 family iso
set logical-systems r4 interfaces lo0 unit 4 family iso address 49.0001.0004.0004.0004.00
protocol isis加入，但level 2 先disable。先用level1來練習
set logical-systems r1 protocols isis interface all level 2 disable
set logical-systems r1 protocols isis interface lo0.1 passive
set logical-systems r2 protocols isis interface all level 2 disable
set logical-systems r2 protocols isis interface lo0.2 passive
set logical-systems r3 protocols isis interface all level 2 disable
set logical-systems r3 protocols isis interface lo0.3 passive
set logical-systems r4 protocols isis interface all level 2 disable
set logical-systems r4 protocols isis interface lo0.4 passive
設定完畢後，也是確認ISIS是否建立完成。

到目前為止確定ISIS都正確設定完成，先驗證其ISIS flooding機制
已logical-system r1來說，可從spf log知道定期會發送訊息的紀錄

其他logical-system也會有相同的訊息。要測試其變動，我們可以把某一台的loopback deactrivate看看，再觀察其發送訊息為何?

由以上藍色部分看，r1 暫時關閉的loopback是會透過LSP給相鄰的logical-system，
之後重複剛剛以上deactrivate lo0.1的動作，在抓取isis spf log的訊息如下:

從以上log來判斷，是R1的lo0.1先deactrivate後，先斷掉r4的isis-neighbor狀態後，r4發送LSP送給相鄰的r2/r3，至於為啥是r4先斷，我覺得可能剛好是在r1跟r4的hello packet剛好在那個時間點沒收到吧!!!
