We have 2 ASR1002's, each with 2 SPA-2CHT3-CE-ATM cards, carrying 4 DS3's. The DS3's are successfully passed over CEM using MPLS between the routers, but the timing is off, so we are seeing high bit errors and the like. After consulting the manual, I see that the SPA cards do not support network timing, which is how we had set it up. It says to use adaptive recovered timing, but when I try to set them as master/slave, it tells me that the SPA card does not support this. I am at a total loss on how to time these units. We had been using a IEEE-1588 timing source, with T1 BITS output to the far-end ASR to synchronize the timing with the near-end, but this will not work either, as the ASR1002 does not output timing on its BITS port. How can these be synchronized when it seems that the cards don't support any timing??
In scaled EVPN deployments it can be wise to name ESI that way to represent the site/physical port/etc it is attached to. Thus on some remote location you can easily verify where particular route/MAC is coming from. Similar to phone numbers, where...
Want to enable Feature EPFT with “routing-protocols-enable”. However ,it is throwing an error and ask to configure the following command: “non-subscriber-interfaces mac” which once enabled drops the traffic without any penalty.
