[ncs 5508] SE card memory resources

[Carlos A. Silva]

Hi,

I'm currently testing an NCS5508 and have a question regarding the memory structure for an eTCAM system. This is actually an 24H-SE card.

We're injecting IPv6 routes from a Spirent traffic generator into an NCS5508 that is working as a border router into a 6PE testbed. We tried generating 200k /48 ipv6 prefixes and expected the router to write them into LEM, but saw the following:

- LEM with 175k mplslabels. Might not be the 200k we were expecting.
- LEM with 0 ip6route.
- LPM with 130k ip6route.

This doesn't sound correct, so I thought I'd ask.

NCS is running 6.1.31.

Thanks!

Hi Carlos,

to be sure I understand your setup, you are trying to inject 200k v6 routes in a 6PE router ?

If confirmed, I suggest you contact your account team. The feature is not tested for such scale,

Kind regards,

N.

Yup, through an eBGP session I send the ipv6 routes to an NCS5k, then turn everything over through 6PE session to a RR.

I'm working with a Cisco SE, btw. Will send him your answer. Thank you very much for taking the time.
