ROUTING OVER WAN

Hi all,

Please I need an urgent help. Please take look at the attached diagram, and the configs - I only copied the relevant ones.
I am presently configuring the links for ISP 1 (the green link). I have configured default routes and redistributed into eigrp on both edge routers (REMOTE OFFICE WAN and CISCO 3560 WAN).
Please look at the routing table, which shows default routes.
The issues I'm having are:

1. from the remote office, I can ping the Head Office gateway as well as the interface GigabitEthernet0/9 (10.151.49.4) on the CISCO 3560 WAN. But I cant reach any network inside the enterprise network. The issue is the same while pinging from the Head Office to the remote office. Only the routers can communicate, I've not been able to connect the two internal networks. Please what else should I configure that I'm leaving out? I need to ensure that the two internal networks can communicate.

2. How best can I configure the ISP 2 link for load balancing and redundancy? Please note the 10.0.0.0/network being used by the two service providers. Would that not be a problem?

Thank you as I expect your inputs.

ROUTING OVER WAN

Your remote office is not learnning any of eigrp route advertised by HO thats the reason not working.Ping for interfaces works since both are part of ISP. You should check with eigrp neighborship on each routers connecting to ISP # show ip eigrp neighbor.

I would guess missing part at ISP end.

Thanks

Ajay
