Issue with BGP neighbors status #573

Open natieitan opened 6 years ago

natieitan commented 6 years ago

I'm using napalm to show and change BGP configuration. I noticed that it always shows 'true' under 'us_up' even if the neighbor is down. I saw on the code, the following:

Uptime should be -1 if BGP session not up

        is_up = True if uptime >= 0 else False

If a neighbor is down there's still a number there, for example: Neighbor V AS MsgRcvd MsgSent TblVer InQ OutQ Up/Down State/PfxRcd 10.0.0.10 4 11055 24061 24287 22 0 0 2w1d 11 10.0.0.14 4 11055 0 0 1 0 0 00:19:49 Idle

Before using napalm I did it in another way, I tracked the last column, true if it's a number, false if it's not, that should be the accurate way

The function:

def represents_int(s): try: int(s) return True except ValueError: return False

The code for the actual check:

                            if represents_int(line.split()[9]):
                                lines_status[isp['name']][4] = 'UP'
                            else:
                                lines_status[isp['name']][4] = 'DOWN'

line - represent each line of the show command: 'show ip bgp sum'

Hi,

Any chance someone can look at that?

dbarrosop commented 6 years ago

given that you seem to have the solution more or less figured out, would you mind sending a PR?

ktbyers commented 6 years ago

@natieitan Can you get me the output from these three commands?

show bgp ipv6 unicast neighbors
show bgp ipv4 unicast neighbors
show bgp all summary

and also the OS version and model number that the output came from.

That's from my lab [it's easier to send that]: ROM: Bootstrap program is IOSv System image file is "flash0:/vios-adventerprisek9-m"

@dbarrosop I'm having hard time understanding the regex, I need to replace the row from "Up/Down" to "State/PfxRcd"

@natieitan We can take this data you provided and incorporate it. I think that BGP code is pretty complex so if you can't complete the PR...no worries.

Ping me if I forget to do this.
