Any idea how to manage/unmanage BGP Sessions

Hello all,

We are managing BGP session with 2 endpoints today. That means only BGP sessions where both end equipement are discovered by NPM are managed. Now we have a request to manage as well BGP sessions to other providers.
As we are not allowed to do discovery on other providers equipement we configured NPM to manage all BGP session.

Problem: only a selection of BGP session with 1 endpoint should be managed.
We tried to figure out the BGP session description (analog to ifDescr for interfaces). Like that we could check in the custom-end script the BGP session description and set BGP sessions with a special flag "UNMANAGE BGP SESSION" to unmanaged. But there is no entry in the MIB for bgp session description.

check on device:
#sh bgp all neighbors x.x.x.x
For address family: IPv4 Unicast
BGP neighbor is x.x.x.x, remote AS XXXX, external link
Description: BGP-sess. ADA wish to see this
BGP version 4, remote router ID x.x.x.x
BGP state = Established, up for 1w0d


Has anyone a workarround for such a monitoring?

Thanks,
ada
