How to configure BGP and routing for new VLANs

[christopher_hall]

I'm looking for some basics for configuring BGP. I do have a couple docs on BGP, but apparently I'm missing something.

Here's my scenario:

Two sites: site1 and site2

Switches: Catalyst 3560s

Router:

2811 == 10.20.102.10

VLANs:

VLAN10 == 10.20.102.1 (primary data vlan)

VLAN4== 10.20.100.1 (san replication)

I am trying to create a new vlan and set it up to update via BGP. The traffic will replicate to site2, but I'll hold off on those details for the moment. As I understand, I would create the vlan as such:

switch(config)#vlan 4

switch(config-vlan)#exit

switch(config)#

Next, I would:

switch(config)#interface vlan4

switch(config-if)#ip address 10.20.100.1 255.255.255.0

etc...

I have setup an interface on the router:

int F0/0.100 == 10.20.100.10

For BGP, I've configured:

router bgp <as>

neighbor 10.20.100.10 remote-as 65342

address-family ipv4

neighbor 10.20.104.10 activate

network 10.20.100.0 mask 255.255.255.0

I've not added any static routing. Looking at examples in our own config, it doesn't appear to require it. The switch is a layer 3, yet, i can't ping the 10.20.100.10 address from the switch and I'm not sure why.

The question is how do I create a new vlan and set this network up so that it updates in bgp?

I'll bring in the site 2 info (which will have another vlan setup) when I can get this running/updating properly.

Been on here quite a bit lately;) Thanks for the help!

Um, ignorance? When you say peering, is that statement something like

neighbor a.b.c.d ...etc?

Yes, exactly. Although you are applying a filtering route-map to one of the peerings.

I must admit, and i mean no offence by this, but from this post and the last post you do seem to have a very complicated setup but having said that without knowing the full topology it may be needed.

Difficult to say but there do seem to be quite a few weird things going on.

We do have some complex things going on in our network. I'm going to pick up a book or two, dig into bgp/routing a bit and post back.

In the end, we had some incorrect IPs in the mix.
