As in the attached diagram at Router A, Traffic from Network 1 to Network 2 is taking path A-D. But in case of the failure on A-D link, Traffic must switchover to path A-B-D. A,B and D are the Cisco 7606 and actiing as MPLS P routers. Traffic engineering tunnels are UP between Network 1 & 2.
OSPF is the IGP runnung.
how can we test how much time the router (A) took to switch between paths, from (1/1) to (2/1) in milli seconds ?
in addition to looking to the log timestamps as suggested by Mahesh, if this a testing lab scenario and you have a traffic generator instrument, you could send traffic from network1 to network2 doing a frame loss test.
Given a constant TX packet rate (i.e. for example 1000 packets/s) the number of packets lost during TE FRR switchover will give you a measure of network convergence time from the point of view of user traffic,
In EVPN A/A + IRB both PE in same EVI have BVI playing a default GW role. Its not supported to have BVI to be shutdown on one of PEs, In this case if if traffic hit this PE with DMAc equal to BVI Custom MAC, then it will drop this traffic du...
