i was in prague, and was able to make everything work like a charm :D :D
now, i have a question about multihoming & high availability.
since i have TWO cogent connections, i have try the following setup (remember, the current WORKING setup is c1->fw1, c2->fw2 + carp)
c1 –> switch --> fw1 (gateway1)
c2 --> switch --> fw1 (gateway2)
aggr_gateway: gateway1 + gateway2 used as lan gateway, with option 'member offline'
bgp with 2 neighborhood
i have configured a group, two cogent neightborood, 2 firewalls rule and on bgp log i see
that my routes get announced on BOTH cogent connection.
i can navigate, and receive packet (i suppose that it's the correct behaviour hehehe)
now, if i unplug c1 from the switch, i can still 'exit' from behind firewall (i have set a gateway with redundancy, so c1 gw goes offline, and traffic switch to c2)
but the INCOMING packet are lost (most of them)
jsut to give you an idea, if i try to reach from public internet a webserver behind firewall (on my /25 network)
pages get serverd 1 every 100 request :D
it's that normal?
on openbgp pdf (http://www.openbsd.org/papers/linuxtag06-network.pdf)
this 'config layout' is in page 5, and i have followed the diagram quite strictly.
i also can confirm that if both cables are connected everything work, it's basically when i unplug one cable that things goes wrong (so maybe, it's not how high availability on 2 connection can be achived)
this tests are pointless, i know, cos i am using TWO cogent cable, but i want to get a level3 cable to setup a real high aviability, so this one should
be a good test.
tnx for your assistance
