ROS2.9做策略路由是不是方便了,还是我理解错了?
官方的例子就是这么简单,难道真的就这样就行了吗 接着下面是关于负载均衡的 这是最后一种测路路由,不过这个例子是双内网到双外网Standard Policy-Based Routing with Failover
This example will show how to route packets, using an administrator defined policy. The policy for
this setup is the following: route packets from the network 192.168.0.0/24, using gateway 10.0.0.1,
and packets from network 192.168.1.0/24, using gateway 10.0.0.2. If GW_1 does not respond to
pings, use GW_Backup for network 192.168.0.0/24, if GW_2 does not respond to pings, use
GW_Backup also for network 192.168.1.0/24 instead of GW_2.
The setup:
Configuration of the IP addresses:
ip address> print
Flags: X -disabled, I -invalid, D -dynamic
# ADDRESS NETWORK BROADCAST INTERFACE
0 192.168.0.1/24 192.168.0.0 192.168.0.255 Local1
1 192.168.1.1/24 192.168.1.0 192.168.1.255 Local2
2 10.0.0.7/24 10.0.0.0 10.0.0.255 Public
ip address>
To achieve the described result, follow these configuration steps:
1.
Mark packets from network 192.168.0.0/24 with a new-routing-mark=net1, and packets from
network 192.168.1.0/24 with a new-routing-mark=net2:
ip firewall mangle> add src-address=192.168.0.0/24
\
\... action=mark-routing new-routing-mark=net1 chain=prerouting
ip firewall mangle> add src-address=192.168.1.0/24
\
\... action=mark-routing new-routing-mark=net2 chain=prerouting
ip firewall mangle> print
Flags: X -disabled, I -invalid, D -dynamic
0 chain=prerouting src-address=192.168.0.0/24 action=mark-routing
new-routing-mark=net1
1 chain=prerouting src-address=192.168.1.0/24 action=mark-routing
new-routing-mark=net2
ip firewall mangle>
2.
Route packets from network 192.168.0.0/24 to gateway GW_1 (10.0.0.2), packets from
network 192.168.1.0/24 to gateway GW_2 (10.0.0.3), using the according packet marks. If
GW_1 or GW_2 fails (does not reply to pings), route the respective packets to GW_Main
(10.0.0.1):
ip route> add gateway=10.0.0.2 routing-mark=net1
\
\... check-gateway=ping
ip route> add gateway=10.0.0.3 routing-mark=net2
\
\... check-gateway=ping
ip route> add gateway=10.0.0.1
ip route> print
Flags: X -disabled, A -active, D -dynamic,
C -connect, S -static, r -rip, b -bgp, o -ospf
# DST-ADDRESS PREFSRC G GATEWAY DISTANCE INTERFACE
0 ADC 10.0.0.0/24 10.0.0.7 Public
ADC 192.168.0.0/24 192.168.0.1 Local1
ADC 192.168.1.0/24 192.168.1.1 Local2
A S 0.0.0.0/0 r 10.0.0.2 Public
A S 0.0.0.0/0 r 10.0.0.3 Public
A S 0.0.0.0/0 r 10.0.0.1 Public
ip route>
如果真的这么简单,那实在是太好了,吼吼~~~~~
策略+负载均衡就这么简单??????
我现在没有真实环境做测试,谁有条件的试验一下啊!!!
这是在VM下,192.168两个网段模拟外网,10.0.0.1/24模拟内网,
然后192.168.65.1这个网关负责总带宽的2/3
192.168.183.1负责总带宽的1/3
比如192.168.65.1有50M的带宽,192.168.183.1有25M的带宽,它们之间的比例是2:1
这就是说我们配置负载的时候不能瞎配,得安比例分配,大家明白我得意思吧。
不明白自己去看官方文档,E文得很难懂。
2.9真得变了很多,可以添加多个默认网关,而且没有IS了,现在变成了AS
A-活动的,也可以说活跃的 S-静态的
[ 本帖最后由 jiangjames 于 2005-8-30 04:47 AM 编辑 ] 自己顶一下,哈哈 期待有条件的试验一下公布结果. 等我有了KEY,我会第一个试验。 看文档,这个不叫策略路由。。。 看了一会,还是觉得自己没有弄懂啊. 这是负载平衡吧,好象没有策略由~~~ 好啊,就等老大来做好试验了 这是负载均衡?我得试试~!刚好我有一条10M电信光纤和一条20M电信光纤…… 结果呢、??????????
