繼續 OSPF 進度
先把 PROSRC_OSPF_2G 打開
# PROSRC_BRCTL_LAN2 is not set
PROSRC_VLAN=y
# PROSRC_OSPF is not set
-# PROSRC_OSPF_2G is not set
+PROSRC_OSPF_2G=y
PROSRC_SMTP=y
PROSRC_RIP_2G=y
# PROSRC_EMMC is not set
1015
先來作一些實驗
搭配這個 /etc/quagga/ospfd.conf
!
interface lan
!
router ospf
network 192.168.1.1/24 area 0.0.0.1
確定能在 lan 端使用 Wireshark 抓到 OSPF packet
1045
之前自己的 implementing 對 ospf 的 configuration 有所誤解
像以下的 /etc/quagga/ospfd.conf
!
interface lan
ip ospf authentication message-digest
no ip ospf message-digest-key
!
router ospf
network 192.168.1.1/24 area 0.0.0.1
利用 ospfd -d -u root 執行會出錯
root@M300-S-E:~# ospfd -d -u root
*** Error reading config: There is no such command.
*** Error occured processing line 4, below:
no ip ospf message-digest-key
就是說沒 no ip ospf message-digest-key 這 command
看來 no 的意思就是不要有 ip ospf message-digest-key 的意思
奇怪的是 no ip ospf cost 又可以 work...
!
interface lan
no ip ospf cost
!
router ospf
network 192.168.1.1/24 area 0.0.0.1
決定只要是 no 開頭的 OSPF command 都不用
1120
先來個小修改

- enable the OSPF compile flag
- fix some OSPF configuration file error

這樣的版本搭配以下的 configuration file
root@M300-S-E:~# cat /etc/quagga/ospfd.conf
interface lan
router ospf
redistribute kernel
redistribute connected
redistribute static
redistribute rip
redistribute bgp
network 192.168.1.1/24 area 0
lan 端的 PC 利用 Wireshark 可以收到 OSPF 的 packet
不過只有看到 Message Type 為 Hello Packet (1) 的 OSPF packet
1125
OSPF 的 IP Protocol 相關資訊參考如下
ip protocol number 為 89
記得要在 APP_INPUT 這個 chain 加上一條 ACCEPT rule
IPTF_JOIN_AND_NEW(IPT_UC_APP_IN, OSPF_2G_IPT_INPUT_CHAIN, NULL);
IPTF_I("%s -p ospf -j ACCEPT", OSPF_2G_IPT_INPUT_CHAIN);
這才發現 rip_2g 這個 RIP 2 generation module 也忘了
1140
趕緊加上
commit 501dfee9304ba2de389c6eea54d3c3084659bf7e
Author: jeffrey <[email protected]>
Date: Mon Dec 4 11:39:21 2017 +0800
add a `ACCEPT` rule for RIP and OSPF in chain `APP_IN`

補一下 OSPF 的 debug
例如像以下的 configuration
root@M300-S-E:~# cat /etc/quagga/ospfd.conf
interface lan
router ospf
redistribute kernel
redistribute connected
redistribute static
redistribute rip
redistribute bgp
network 192.168.1.1/24 area 0
debug ospf packet all send
debug ospf packet all recv
log file /tmp/ospfd.log
在 shell 直接使用
ospfd -d -u root- start ospfd
killall ospfd- stop ospfd
注意不能使用
/etc.init.d/quagga start ospfd- start ospfd
/etc.init.d/quagga stopt ospfd- stop ospfd
否則無法送出 packet... 原因不明
log 如下
root@M300-S-E:~# cat /tmp/ospfd.log

找個兩台 m300 lan 對接觀察一下 log
1400
兩台 M300 配置如下
+-------------+ +--------------+
| M300-A | lan +--------+ lan | M300-B |
| +-----------------+ switch +-----------------+ |
| | 192.168.1.1 +--+-----+ 192.168.1.100 | |
+-------------+ | +--------------+
|
+--+-----+
| PC |
+--------+
PC 端用來利用 Wireshark 觀察封包
M300-A 使用的 configuration 如下
interface lan
router ospf
redistribute kernel
redistribute connected
redistribute static
network 192.168.1.1/24 area 0
debug ospf packet all send
debug ospf packet all recv
log file /tmp/ospfd.log
M300-B 使用的 configuration 如下
interface lan
router ospf
redistribute kernel
redistribute connected
redistribute static
network 192.168.1.100/24 area 0
debug ospf packet all send
debug ospf packet all recv
log file /tmp/ospfd.log
終於看到除了 Hello Packet (1) 之外的 packet 了
不過後續就又只剩下 Hello Packet (1)
兩邊的 log 利用 gist 存一下
至於 Wireshark 抓取的方包就先存下來以利後續分析 - D:\m300\doc\2017-12-04.ospf_test.pcapng

讓 OSPF 的 web page 多一些描述好讓使用者知道自己在設定什麼東西

- more user friendly the OSPF web page
- show 'Redistribute OSPF routes' option in RIP web page

明天可以來寫 OSPF 的 proposal 了
