I have two 2951 routers which we are replacing with 1841 routers and they are waiting to put in production environment.
The environment including number DMVPN sites with EIGRP, many s2s vpns as well as client vpns. etc.,
1841 routers currently have 12.4(19) K9 bundle, but its taking reboot for every fortnight and creating crash dump.
By observing all these troubles and searched in IOS data sheets I found 12.4(24)T3 is best one for new 2951 routers.
2951 routers already have 15.0(1r)M1 (image c2951-universalk9-mz.SPA.150-1.M1.bin)
Now i am thinking to choose the one better IOS. Can any one suggest me which IOS is better to procceed.
