Removing BGP Site Of Origin SOO Community

Dear All

 

Once a BGP site-of-origin (SOO) has been applied to incoming routes, is there any way to delete it on announcements to other peers? For example:

 

router bgp 1
address-family ipv4 vrf vf-custA
neighbor 100.1.1.2 remote-as 65000
neighbor 100.1.1.2 as-override
neighbor 100.1.1.2 soo 65000:1

If I then want to stop an SOO extended community of 65000:1 being advertised deeper into the "service provider" iBGP network, can I do this?

 

ip extcommunity-list expanded CL-DROPSOO permit ^65000:1$

route-map RM-OUT-DROPCOMM permit 10
set comm-list CL-DROPSOO delete
exit

[...]
neighbor 192.168.1.1 send-community both
neighbor 192.168.1.1 route-map RM-OUT-DROPCOMM out

Kind regards

 

James.
