Configuring an external route import policy on Switch C

  1. Configure external static route.

    admin@XorPlus# set protocols static route 192.168.6.0/24 next-hop 172.25.150.245
admin@XorPlus# commit
Waiting for merging configuration.
Commit OK.
Save done.
admin@XorPlus#

  2. Configure policy to import external route

    admin@XorPlus# set policy policy-statement static term 1 from protocol static
admin@XorPlus# set policy policy-statement static then accept
admin@XorPlus# commit
Waiting for merging configuration.
Commit OK.
Save done.

  3. Use policy on ospf

    admin@XorPlus# set protocols ospf4 export static
admin@XorPlus# commit
Waiting for merging configuration.
Commit OK.
Save done.
admin@XorPlus#

  4. Check route table on Switch A. There will be route entry 192.168.6.0/24

    admin@XorPlus# run show route forward-route ipv4 all
