ospf lab 4...

pretty pictures...

since it's frame, i'll be a nice guy and post the configs... go ahead and scrape, vultures...

but first a couple of things...
i'm never going to post the gns3 files, so forget it... why?

because you should build it yourself, that's why...  i build everyone from scratch, and you should too... wax on, wax off, danielson... you some kind of girl or something... frame technique; no defense...

also, here's to everyone who bitches about frame... don't do that... i used to think they still teach it because it's tricky and causes routing protocols to do weird shit, which is partially true, i suppose... but there's more... i believe that frame relay lays the foundation for a solid understanding of mpls... learn balance... and if you don't buy that, i don't care...

east#ping 10.1.23.3
Type escape sequence to abort.
Sending 5, 100-byte ICMP Echos to 10.1.23.3, timeout is 2 seconds:
.!!!!
Success rate is 80 percent (4/5), round-trip min/avg/max = 4/22/44 ms

now for the nail biter...  the interfaces never match the lab, so the translation part always sucks... a single mistake, and you are troubleshooting till the cows come home... here it is... but if you are doing it with gns3, your interfaces can match mine, you lucky bastards... i use 7200's and a 3640 for the frame switch, in case you hadn't realized...

of course it's correct... i'm michael the network cat, you dumbasses... see below...

now add ospf, the networks, and make the loopbacks p2p...

you can do that yourselves...

change the priority on east and west  to 0 so that hq is guaranteed the dr...

west(config-if)#int s1/3
west(config-if)#ip ospf pri 0

east(config)#int s1/2
east(config-if)#ip ospf pri 0

the point of all this is that the default network type is nonbroadcast, so we have no adjacencies but we'll accomplish this with neighbor statements... simply, it can be performed on a single router, but best practices dictates it on all three..

hq(config)#router ospf 1
hq(config-router)#neigh 10.1.123.2
hq(config-router)#neigh 10.1.123.3
hq(config-router)#
Aug 12 19:58:44: %OSPF-5-ADJCHG: Process 1, Nbr 10.1.3.1 on Serial1/0 from LOADING to FULL, Loading Done
Aug 12 19:58:44: %OSPF-5-ADJCHG: Process 1, Nbr 10.1.2.1 on Serial1/0 from LOADING to FULL, Loading Done
hq(config-router)#

do it on the other 2 anyway, like good little buttsticks...

west(config)#router ospf 1
west(config-router)#neigh 10.1.123.1
west(config-router)#

east(config)#router ospf 1

we'll finish tomorrow... i've been at it since 6 am...
