I have a problem.I know interface aggregation works when the interfaces you are aggregating are going to same device.Is it feasible to create an aggregate interface when interfaces are connected to different devices.Lets say I have 3 routers ,A,B,C.RTA has two gige interfaces.Gigi0/1 is connected to RTB and gigi0/2 is connected to RTC.i tried creating aggregate interface on RTA.But this created lots of degradation.Is is that traffic gets split between this two interfaces or loop ? Am not using any switch here.
An aggregate inteface is a Port-channel interface and is part of the Ether-channeling feature. On a multilayer switch, you can configure a Port-channel interface for Layer3 operation and assign it an ip address. Load balancing will be implemented using an algorithm specific to Etherchannel, but the next hop will always be the same router.
When you connect 2 interfaces of RouterA to 2 different routers, it is already not an aggregate interface.
In this case you need to put them into different ip subnets on Router A and it maybe called an alternate route to some remote subnets if it really leads to the same subnets.
As Giuseppe says, this solution can be used for load balancing between alternate routes (usually alternate next hops). In this case load balancing is accomplished by the routing protocol according to the protocol configuration.
This is actually a pretty cool feature, i didn't even know it existed until I was looking for a solution to advertise a subnet (prefix in BGP talk), only if a certain condition existed. This is exactly what conditional advertisements does
