[asterisk-users] 3 locations 3 vpns

[Tomáš Holý]

Hi,
I would use some dynamic routing protocol. For this purpose would be better don't mix L2 and L3. Then you can use OSPF or RSTP.

Let's say the second asterisk is setup at C and that loses connectivity with B (while A still have it's tunnel up), that will result both A and C are separated from B also in this case all of A's phone traffic is routed through C.
