juniper-bgp配置命令（备忘）

Posted 2020-09-27

ex4550与防火墙旁路BGP牵引配置

创建as域及对端

set routing-options autonomous-system 65533

set protocols bgp group ebgp type external

set protocols bgp group ebgp neighbor 10.0.0.2 multihop

set protocols bgp group ebgp neighbor 10.0.0.2  import bgp_permit

set protocols bgp group ebgp neighbor 10.0.0.2  export bgp_deny

set protocols bgp group ebgp neighbor 10.0.0.2  peer-as 65534

编写需要发布/不发布的路由，需要引入的路由。

set policy-options policy-statement bgp_deny term 1 from route-filter 0.0.0.0/0 orlonger

set policy-options policy-statement bgp_deny term 1 then reject

set policy-options policy-statement bgp_permit term 1 from route-filter 1.0.0.0/24 upto /32

set policy-options policy-statement bgp_permit term 1 then accept

set policy-options policy-statement bgp_permit term 2 then reject

创建策略路由指定回注端口。

set firewall family inet filter zzidcip term pass from destination-address 1.0.0.0/24

set firewall family inet filter zzidcip term pass then routing-instance zzidcip

set firewall family inet filter zzidcip term 1 then accept

set routing-instances zzidcip instance-type forwarding

set routing-instances zzidcip routing-options static route 0.0.0.0/0 next-hop 172.31.4.5

主策略路由内引入附表 。

set routing-options rib-groups celve import-rib zzidcip.inet.0

端口应用策略路由。

set interfaces xe-0/0/20 unit 0 family inet filter input zzidcip

set interfaces xe-0/0/20 unit 0 family inet address 10.0.0.1/30
