Hi!
You can find conversation in HUB:
UDLD - you can use ELSM https://documentation.extremenetworks.com/exos_22.2/EXOS_21_1/Status_Monitoring/c_using-elsm.shtml
IPv6 RA - https://community.extremenetworks.com/extremeswitching-eos-230140/ipv6-ra-guard-support-for-eos-or-exos-7536550
https://documentation.extremenetworks.com/exos_22.2/EXOS_21_1/IPUnicastv6/c_ipv6-router-advertisement-filtering.shtml
All Summit, BD8K, and BDX8 platforms are supported. However, there are per-platform limitations on how many IPv6 extension headers can be parsed while still matching the supplied
ICMP (Internet Control Message Protocol) type:
Up to 2 extension headers: X670-G2, X770
0 extension headers: Summit platforms
Thank you!
