Issue/Introduction

We have implemented Enterprise VPN Manager in Spectrum and we have noticed that some of the ASN numbers are showing up as a negative number.

Environment

Spectrum 25.4.6 and earlier

Enterprise VPN Manager

Cause

The standard MIB2 BGP4 mib and the Cisco BGP4 Mib have different ASN ranges.

 

bgpLocalAs OBJECT-TYPE

               SYNTAX INTEGER (SIZE (0 .. 65535))

               ACCESS read-only

               STATUS mandatory

               DESCRIPTION

               "The local autonomous system number."

               ::= { bgp 2 }

 

cbgpLocalAs OBJECT-TYPE

               SYNTAX InetAutonomousSystemNumber (0 .. 4294967295)

               ACCESS read-only

               STATUS current

                DESCRIPTION

               "The local autonomous system (AS) number."

               ::= { cbgpGlobal 2 }

 

 

Resolution

This will be fixed in a future Spectrum release post 25.4.6 with a database change.
