Hi George, No we are not looking at redistriubtion, the topology we are trying to depict is somthing like the below case. We have 2 sites sites connected to each other over normal router using static route now the interface of the router connected to the lisp sites are learned over lisp protocol in the EID space so to forward the traffic to the second site we are pointing a static route to the route learned via lisp( which is the next hop) I hope the scenario is clear. Thanks, Rijo

The wan interface is a dedicated interface mainly for ISP, but the issue is that ISP requires this setup hence we need to make sub interface.
the load on the cpu doesnt cross 60% as far as i saw it.
this was noticed with IOS 15.4(3)-M2/ IOS 15.4(3)-M3 with standby router and active router was having no issues at all.
Once we upgraded both routers to 15.4(3)-M4 the standby router input queue has become nore stable than before but the active routers queue gets filled up so fast that means even after increasing the queu size to 24000 it got filled to 2000 with 10 mins.

We have been trying to implement NAT box 2 box between two 3925 routers,
WE have successfully configured it, but because of the assymetric routing configured on the wan interface
There is a problem that the input queue of the wan interface gets filled in the standby router, after upgrading the router this has stopped but we also upgraded the primary router and now the input queue of the wan interface in the primary router gets filled.
the config is as shown below
