Deploying Fully Routed OSPF Enterprise Network

[superlubis]

Hi,

Theres a cisco document about building a fully routed enterprise network with ospf or eigrp out there. I have a question in internet layer based on picture below :

1. interface belong to area 0 is interface connecting dist to core/backbone, is this correct ?

2. interface belong to ospf area 200 is interface connecting dist to firewall and all firewall interface, is this correct ?

3. if theres is an edge router connect to firewall and that edge router connect to isp with bgp let say private bgp and my network publish class c ip address, i dont understand to distribute ospf to bgp ? where do i distribute, in edge router ? do my router to firewall have point-to-point public ip address ?

Thx

1. yes

2. yes

3. you need to configure the edge device on your network as an ASBR.

yes that document i read, i'm asking about configuration in edge router and firewall.

if my edge router have private bgp and advertise public ip, let say 65101 and my router have two interface, the first one connect to firewall and the second connect to my isp

router bgp 65101

no synchronization

bgp log-neighbor-changes

network 4.4.4.0 mask 255.255.255.192

neighbor 192.168.131.97 remote-as 17974

neighbor 192.168.131.97 description LOCAL

neighbor 192.168.131.97 soft-reconfiguration inbound

no auto-summary

interface GigabitEthernet0/0

ip address 192.168.131.98 255.255.255.252

no cdp enable

my question is my edge router connection to firewall using public ip ? let say edge router(4.4.4.1) --> firewall (4.4.4.2) ?

how to distribute ospf ? routing config in firewall and edge router ?

thx
