今天先單就 M300 本身 nhrpd 啟動的問題追出根源

M300 reboot

先找出最快複製出昨天問題的步驟

找一個方法讓 winston 也能從遠端來控制 Cisco 2951

設定 Cisco 2951 的 IP - 192.168.1.200

Router>enable
Router#configure terminal
Enter configuration commands, one per line.  End with CNTL/Z.
Router(config)#interface GigabitEthernet 0/0
Router(config-if)#ip address 192.168.1.200 255.255.255.0
Router(config-if)#no shutdown

設定 enable secret - 否則 telnet 近來也無法使用 enable - enable secret: proscend

Router>enable
Router#configure terminal
Enter configuration commands, one per line.  End with CNTL/Z.
Router(config)#enable secret proscend

設定 telnet - password: proscend

Router(config)#line vty 0 3
Router(config-line)#transport input telnet
Router(config-line)#password proscend
Router(config-line)#exit
Router(config)#exit
Router#write memory
Building configuration...
[OK]

這樣便可從遠端 telnet 進來

User Access Verification

Password: (proscend)
Router>enable
Password: (proscend)
Router#configure terminal
Enter configuration commands, one per line.  End with CNTL/Z.
Router(config)#

1055

簡單設定 Cisco 2951 的 GRE with NHRP

Router>enable
Password: (proscend)
Router#conf t
Enter configuration commands, one per line.  End with CNTL/Z.
Router(config)#interface tunnel 0
Router(config-if)#ip address 10.1.1.200 255.255.255.0
Router(config-if)#ip nhrp network-id 1
Router(config-if)#tunnel source 192.168.1.200
Router(config-if)#tunnel mode gre multipoint
Router(config-if)#no shutdown

M300 重開機再來一次

gre

ip tunnel add gre1 mode gre remote 192.168.1.200 local 192.168.1.1
ip link set gre1 up
ip addr add 10.1.1.1/24 dev gre1

把 nhrpd 叫起來

rm /etc/quagga/nhrpd.conf
touch /etc/quagga/nhrpd.conf
nhrpd -d

nhrp 設定

透過 vtysh

root@Cellular Router:~# vtysh

感覺可以直接修改 /etc/quagga/nhrpd.conf 然後再啟動 nhrpd

透過觀察 log 看看有沒有機會

找一點設定的靈感
