Entropy Label Capability

sbattula301 · ‎06-21-2016

In Cisco ASR 9006, I had enabled Entropy Label, under mpls ldp "entropy-label" , commit goes through fine. but I don't see ASR9006 is generating ELC TLV for its own system FEC.

7x50 ------------------------ASR9006 -----------------------7x50

(10.20.1.2) (10.20.1.8) (10.20.1.3)

In the above both 7x50 are enabled with ELC. they are generating ELC for their system FECs'

Hi,

It seems this is not supported in ASR9k yet. This appears to be supported on CRS.

As per below doc

http://www.cisco.com/c/en/us/td/docs/routers/asr9000/software/asr9k_r4-2/mpls/command/reference/b_mpls_cr42asr9k/b_mpls_cr42asr9k_chapter_01.html#wp2525564653

it is supported in ASR9K from 5.3.2 onwards, but that seems to be not working.

Thanks,

Srinivas

Hi,

I think it should be a documentation issue. Entropy label was targetted for CRS (P routers) on 5.3.2 as mentioned in the document. The CLI is available but the feature is not supported in ASR9k.

Hi,

Looks like in CRS also this support is not there. We verified with CRS latest version.

Thanks,

So what’s the conclusion on this one please?

Do Cisco ISP products support entropy labels or not? And if yes is it compatible with other vendors?

Thank you

Did you try flapping the LDP neighbor. what is the XR version you are running

Thanks
