I've been spending the last week or so troubleshooting some (maybe related, but probably not) issues with Quagga. I have a test router - 7204VXR-NPEG2 running 12.4(24)T6 - with a single BGP session to a Quagga host. The only BGP session on the 7204 is with the Quagga box. This is an eBGP session. There is literally zero policy configured on either side, yet I get this without fail in
show ip bgp neighbor x.x.x.x output:
Outbound Inbound Local Policy Denied Prefixes: -------- ------- Bestpath from this peer: 19270 n/a Total: 19270 0
Coincidentally (or maybe not?) this number is always the same as the number of prefixes that I am receiving from the peer (
show ip bgp summary) There's a couple reasons why this is really puzzling:
1) Like I said, there is no policy. This is my BGP/neighbor config:
router bgp XXXXX no synchronization bgp router-id X.X.X.X no bgp enforce-first-as bgp log-neighbor-changes neighbor X.X.X.X remote-as XXXXX neighbor X.X.X.X next-hop-self neighbor X.X.X.X soft-reconfiguration inbound no auto-summary
2) The 7204 is not announcing anything - it's only meant to receive prefixes.
Anyone care to shed some light on what this means? Is this normal/expected output? A google search only yielded me one tidbit of information pulled from CCO:
- Bestpath from this peer
Displays inbound denials because the bestpath came from the local router.
This would make sense ... for inbound. What about outbound? I can easily see this being a stupid bug, but figured I'd reach out to other folks to see if they'd seen this before.
