I have two routers 1841 with "c1841-advsecurityk9-mz.124-13.bin" IOS software and two ADSL connections each, and I whant to configure a vpn with load balancing (multilink) can cisco routers do this and how ??
I dont have an ADSL card on the routers. the two connections are form differents providers and the ADSL modems are connected to the routers through the Ethernet ports.
VPN and loadbalancing will not be possible however you can get redundancy with the VPN. If you configure one ADSL connection as primary default gateway and the other as secondary (with higher AD) it should be acheivable. Ofcourse we'll have to do a li'l more brainstorming in order to get it work.
Can I do it by another way (I heared about different Cisco technology like DMVPN or GETVPN) can theses technologies do the multilink and how, or I have to change my routers or IOS versions or it is impossible to do it with cisco devices
