[AusNOG] Vyatta - Accepting /24 from Customer and advertising to upstream

[Daniel Watson]

Hi Damien

Ive now set an import prefix list for this, altho it was accepting it before regardless :D

We are setting getting the route from the customer, but still not being sent on to our 2 upstream advertisements :S

I'm sure someone who knows 100% will reply when they all wake up by two things to try..

1) on neighbor 103.18.204.242, there's no prefix-list import. I'm not sure whether this will just accept *everything* (this is bad mmmkay), or whether it will accept nothing at all.. Would be best to add a prefix list to accept the /24 from the customer.

Though you can check this by doing:
show ip bgp neighbors 103.18.204.242 received-routes

(Note misspelling of neighbours, this throws me every time!)

And see if you're receiving the route

I'd also check if you're sending the route on to your upstream.

aka

show ip bgp neighbors 1.0.4.73 advertised-routes

2) Have you told your upstream about the new prefix (and supplied them with your customer's LoA), and have they confirmed that they and all their upstreams are accepting it via you? If not, they're not going to accept it from you (unless they're a bit dodgy..).

Two things to check on anyway :)

Regards,
Damien

Hi Guys

We are accepting 203.27.101.0/24<http://203.27.101.0/24> via AS133196 to our router
We are trying to advertise this router that we are getting on our BGP session to 133196 over to our upstream provider at 1.0.4.73 & 1.0.4.74

However our upstream provider are not getting those routes from us

I have uploaded a sample of our configuration to http://glovine.com.au/daniel/melbourne.txt

Can anybody point out the issue with 203.27.101.0/24<http://203.27.101.0/24> sending upstream?   First time newbie doing this part :D
