Hi,
in close future i'll have to transition Frame Relay to L3VPN WAN links. I have two available routers and my dilemma is next:
1) i can connect my ISP's optical link directly to my primary router - in that case i can use simple hot standby (backup) router, with the same configuration as primary router, and manually switch cable if primary router goes down. Here, i have single point of failure which is primary router.
2) i can use L2 switch to transport ISP's vlan to both routers and use HSRP between them. But in this case i also have single point of failure which is the L2 switch, and if it fails i'll also have to manually switch cable to another switch!
What are the benefits/drawback of 1 or 2, your opinion?
Thanks in advance
