Re: Catalyst 3560E best configuration for ring topology
Rapid STP 802.1W that can be enabled using Rapid PVST or MST 802.1s is much faster then RIPv2.
However, the size in terms of number of devices can require to increase the lifetime of STP messages (max-age) to avoid that in case of failure the network can become partitioned for this reason.
To be noted RIPv2 has also a limitation of only 15 useful next-hops so a L3 solution if the number of devices is great should use a different routing protocol like EIGRP or OSPF, using fast hello timers or BFD.
However, you can carry Vlan tagged frames over a L2 network.
There are methods to carry Vlan tagged traffic over an IPv4 methods but they are not available on C3560E (L2tpv3 for example)
