6wind Turbo Router 2的GRE隧道和BGP设置

本文中我们来演示一下在新的6wind测试路由器和现有的一台RouterOS之间打一个隧道,然后做一个简单的BGP配置。

6wind一侧:

  • 公网IP:1.1.1.1
  • 隧道内IP:192.0.2.1/30和2001:db8::2/127

RouterOS一侧:

  • 公网IP:2.2.2.2
  • 隧道内IP:192.0.2.2/30和2001:db8::3/127

GRE隧道

6wind一侧,配置和iproute2非常类似,没有什么好说的。没有用过Linux上GRE的朋友们别忘了ttl 255,不然一会儿配BGP的时候就得multihop了。

james-test-router0> edit running
james-test-router0 running config# vrf main
james-test-router0 running vrf main# interface gre tunnel1
james-test-router0 running gre tunnel1#! local 103.121.209.165 remote 45.77.27.154
james-test-router0 running gre tunnel1# ttl 255
james-test-router0 running gre tunnel1# ipv4 address 192.0.2.1/30
james-test-router0 running gre tunnel1# ipv6 address 2001:db8::2/127
james-test-router0 running gre tunnel1# commit
Configuration committed.
james-test-router0 running gre tunnel1# commit
Configuration committed.

RouterOS一侧, 也没有什么好说的。

/interface gre
add !keepalive local-address=45.77.27.154 name=6wind-test remote-address=103.121.209.165
/ip address
add address=192.0.2.2/30 interface=6wind-test network=192.0.2.0
/ipv6 address
add address=2001:db8::3/127 advertise=no interface=6wind-test

配置完成后ping一下看看隧道通不通。

james-test-router0> cmd ping 2001:db8::3
PING 2001:db8::3(2001:db8::3) 56 data bytes
64 bytes from 2001:db8::3: icmp_seq=1 ttl=64 time=3.64 ms

BGP配置

6wind一侧

james-test-router0> edit running
james-test-router0 running config# vrf main routing bgp
james-test-router0 running bgp#! router-id 103.121.209.165
james-test-router0 running bgp#! as 65500
james-test-router0 running bgp# neighbor 192.0.2.2 
james-test-router0 running neighbor 192.0.2.2#! remote-as 205610
james-test-router0 running neighbor 192.0.2.2# ..
james-test-router0 running bgp# neighbor 2001:db8::3
james-test-router0 running neighbor 2001:db8::3#! remote-as 205610
james-test-router0 running neighbor 2001:db8::3# address-family ipv6-unicast
james-test-router0 running neighbor 2001:db8::3# commit
Configuration committed.

RouterOS一侧

/routing bgp peer
add keepalive-time=10s name=6wind-test-v4 remote-address=192.0.2.1 remote-as=65500 ttl=default update-source=6wind-test
add address-families=ipv6 keepalive-time=10s name=6wind-test-v6 remote-address=2001:db8::2 remote-as=65500 ttl=default update-source=6wind-test

需要注意的是,6wind的BGP配置风格更像Cisco,因为其路由daemon是FRRouting。内存足够的前提下,收个全表肯定不是什么问题。内存压力:
