Hi friends,
I have a question about IP SLA, so here goes.
I'm trying to implement the ip sla by the frame relay
here is my topology
I'm sending g711 packets from R1 to R5
there is a traffic that succesfully sent to R5. The question is, why didn't it detect any latency
this is the ip sla statistics output
R1#sh ip sla monitor statistics
Round trip time (RTT) Index 1
