![]() ![]() Which could be of some use over radio links.įor slow links, under 100Mbps, you may fallback to 3845 or 881/891. Also it is able to route 1,5Gbps in simple setups, and encapsulate up to 600Mbps cleartext, 300Mbps AES-128-CBC. You may even use VRRP or HSRP for an extra redundancy in case one of the box fails.īefore anyone asks, I'd recommend the 7301 because of its compacity, relatively low price and power consumption. The best course of action here would be to buy 4 small routers, such as Cisco 7301 ($400-800 from a decent broker, capable of 1+Gbps depending on the configuration), put one at each link end, interconnect at both end, address a private 元 network (IPv4 or IPv6, doesn't matter here) and establish routed tunnels on top of this square. Then OSPF or IS-IS, but neither will allow unequal cost multipath. Any suggestions?įor fast convergence and active/active links, the best 元 protocol out there is EIGRP. Doesn't require the switch interface to go down, and can be configured with a recovery time period to reduce network flapping. Extreme has EAPS, which does work well but only in a ring architecture which doesn’t really work for our network.īasically, I’m looking for something like spanning tree, that doesn’t have a world of backwards compatibility issues. TRILL and 802.1aq (SBP) seem to be the replacements, but it seems both have lost focus over the past few years and I don't have any switches in the lab that support this. And it really doesn't play nice with intermittent flapping links. Failover time is painfully slow with wireless links that do not drop ethernet link. It is full of backwards compatibility issues. It isn't often, but just often enough to need a backup. I use it to failover to 5 Ghz wireless links when our 80 Ghz or 24 Ghz links go down during heavy rain. Being 2015 and all, you'd think there is a better protocol to replace spanning tree.
