[Observium] BGP LocalAs fails on ASR9K

Hi,

we discovered an issue with CISCO ASR9K and 4byte ASN's - the ASR return "0" when querying the BGP4-MIB parameter "bgpLocalAs". This stops observium from discovering the BGP sessions.

I have done some research and found that Juniper devices seem to have a similar problem which was fixed in the polling / discovery script already.

The same should be done for Cisco. The CISCO-BGP4-MIB included in Observium is somewhat outdated - CISCO introduced a parameter "cbgplocalAs" in a later version which delivers the correct result.

Could you please look into this ?

Thanks

Andre
