routing protocols
ive connected 3 routers together but one main router is connected to the other 2 routers for equal-cost load balancing.
im not sure if i use cisco default encapsulation hdlc or ppp for example, there is a 3rd one but cant remember or is there a particular scenario that would decide this for me?
eitherway the network is setup and can ping as normal.

The encapsulation method doesn't have anything to do with load balancing. If you have two equal cost routes in the routing table from either static or a routing protocol like RIP, OSPF, etc.., you will achieve load balancing. In your scenario, to achieve load balancing, the same subnet would have to be on both routers (the two connected to the main) and the main have two equal cost routes.

im sure when i removed the encapsulation the link went down, so im assuming that although nothing to do with load balancing as you say. i still need one in and presumably should it just be the default setting hdlc. or am i talking crap!!?
No, you are correct, you need encapsulation set to something. By default, HDLC is the encapsulation set on the interface. PPP is an alternative for a point to point connection.

I agree with JFrederick... 1) Keep your (2) NON-main routers on the same subnet, using OSPF should be maintain load balance while allowing those 2 routers to communicate between one another. 2) Enable routing so your route tables are updated if this isnt done already and ensure there is at least (1) independant connection going from ea of the 2 non-main routers to separate interfaces on the main router. This will ensure your load balance and add a diverse route in the event you lose a connection from either of the 2 routers going to your main. Hope this helps.

hi warlock,
well at the moment im using rip and using the command "no ip route-cache" to disable ip fast switching. but you say ospf, is this because ospf has more functions available to it and instead of using the command im using although using with rip. it is a more efficient way of doing it?
and also off of the two other routers i have connected them together via ethernet x-over cable, so im assuming if a router looses a connection with the other router it can gain a secondary connection which im assuming is what you call a redundant connection via the ethernet connected and back through the other router to the main router. if ive explained that correctly. or is this purpose for something else as im just doing what im advised but dont quite get the priniciple behing the ethernet connection, which is on a 10.0.0.0/24 network!!
