今天專心地來做 GRE NHRP
昨天有 build 一版 M300 develop branch 的 image
也用 mfgtool 燒錄好了一片 CPU board
先將 Cisco 2951 開機

john 有急件
M360 的 IP Filter 有一些字眼要修改

繼續 NHRP
先設定 Cisco 2951 的 IP 讓 M300 與 Cisco 2951 能互通

可以開始研究 M300 要怎麼來設定了
1100
參考 Introduction to Multipoint GRE and NHRP
其中的 Dynamic (Hub Side) mGRE using dynamic NHRP 那張圖
左側 Fa0/0 就是我目前的 Cisco 2951
右側就把最上方那當作是 M300 好了
目前我們 Cisco 2951 當成這張圖左側的腳色的話
config 就可以整理成下面的樣子
interface Tunnel87654321
ip address 172.30.96.5 255.255.255.248
no ip redirects
ip nhrp authentication LTEGRE
ip nhrp network-id 87654321
tunnel source tunnel source GigabitEthernet 0/0
tunnel mode gre multipoint
tunnel key 87654321
理論上 M300 如果是一台 Cisco 的 device 的話
config 應該會是像
interface Tunnel0
ip address 172.30.96.6 255.255.255.248
no ip redirects
ip nhrp authentication LTEGRE
ip nhrp network-id 87654321
tunnel source tunnel source 192.168.1.1
tunnel destination 192.168.1.200
tunnel key 87654321
目前的重點就在於我們要怎麼利用目前 M300 上的 Linux 來做出等效的設定
1130
monkeyjj time
要做出 calendar 雖然我可以土法煉鋼
不過畢竟我的時間有限
挑個現成的研究一下有許也不錯
挑個星星最多的 react-big-calendar 來玩玩
1300
回到 NHRP
參考以下
不過先搞定原本 GRE 的部分
左側 Cisco 2951 config 如下
interface Tunnel87654321
ip address 172.30.96.5 255.255.255.248
no ip redirects
ip nhrp authentication LTEGRE
ip nhrp network-id 87654321
tunnel source tunnel source GigabitEthernet 0/0
tunnel mode gre multipoint
tunnel key 87654321
跟 GRE 有關的是
tunnel source tunnel source GigabitEthernet 0/0
tunnel mode gre multipoint
tunnel key 87654321
參考原本 M300 GRE 的 wiki
右側 R5 所需的設定如下
ip tunnel add gre1 mode gre remote 192.168.1.4 local 192.168.1.5 ttl 255
ip link set gre1 up
ip addr add 10.1.1.5/24 dev gre1
如果要模仿右側的 config 的話
interface Tunnel0
ip address 172.30.96.6 255.255.255.248
no ip redirects
ip nhrp authentication LTEGRE
ip nhrp network-id 87654321
tunnel source tunnel source 192.168.1.1
tunnel destination 192.168.1.200
tunnel key 87654321
linux 應該是可以這麼下
ip tunnel add gre1 mode gre key 87654321 remote 192.168.1.200 local 192.168.1.1 ttl 255
ip link set gre1 up
ip addr add 172.30.96.6/29 dev gre1
試試吧
root@Cellular Router:~# ip tunnel add gre1 mode gre key 87654321 remote 192.168.1.200 local 192.168.1.1 ttl 255
root@Cellular Router:~# ip link set gre1 up
root@Cellular Router:~# ip addr add 172.30.96.6/29 dev gre1
root@Cellular Router:~# ifconfig
...

...
再來是 NHRP 的部分
利用 vtysh 來試試
root@Cellular Router:~# vtysh
Hello, this is Quagga (version 1.2.4).
Copyright 1996-2005 Kunihiro Ishiguro, et al.
Cellular Router# configure terminal
Cellular Router(config)#
Cellular Router(config)# interface gre1
Cellular Router(config-if)#
Cellular Router(config-if)# ip nhrp network-id 87654321
Cellular Router(config-if)# exit
Cellular Router(config)# exit
Cellular Router# write file
Building Configuration...
Configuration saved to /etc/quagga/zebra.conf
[OK]
Cellular Router#
唯一找到匹配的只有 ip nhrp network-id 87654321
不過這樣子做員並沒有看到甚麼 nhrp 相關的 config
目前試著啟動 nhrpd 會得到以下的錯誤訊息
root@Cellular Router:~# nhrpd -d
vty_read_config: failed to open configuration file /etc/quagga/nhrpd.conf: No such file or directory
can't open configuration file [/etc/quagga/nhrpd.conf]
我想我可以先朝這個方向努力一下
先把 Cisco 2951 關機
