[c-nsp] ospf question

[Sam Sarkis]

Hi All,

I hope this isn;'t to confusing

My questions is what is the best way to setup OSPF so that each link uses the best available and traffic will reroute if a link goes down. Each of the links have their own ip address and then the local LAN at each site have there own subnet or a couple of subnets (Vlans). Route summarization is not possible.


we have a the following;

Remote Site 1
Router A connects via 100Mb ethernet to Router B (HO)
Router A has a number of dsl connections directly connected via ATM
Router A connects via 100Mb ethernet to Router F (Remote Site3)

HeadOffice
Router B connects via 2Mb E1 to Router E (Remote Site2)
Router B has a number of internal VLAN directly connected
Router B connects to backbone
Router B connects via 100mb Ethernet to Router A (Remote Site1)
Router C Connects to backbone
Router C has dialup ISDN no need for ospf
Router D Connects to backbone
Router D connects to frame relay connected sites no need for ospf
Default Gateway for local network

Remote Site 2
Router E connects via 2Mb E1 to Router B (HO)
Router E connects via 10Mb Ethernet to Router F (Remote Site3)

Remote Site 3
Router F connects via 10Mb Ethernet to Router E (Remote Site2)
Router F connects via 100mb Ethernet to Router A (Remote Site1)



thanks
