On an OS7000, the yipped field gets changed.
Workaround: There is no known workaround at this time.
PR 84500
On an OS7000, once UDP framed is relayed, its TTL value is always set to 32 secs (hex 20)
Workaround: There is no known workaround at this time.
PR 84592
In certain cases, frames get duplicated with UDP Relay on an OS7000.
Workaround:
1. With VRRP, enabling only on one VRRP router (either master or backup) is desirable for any UDP
relay service to avoid UDP frames being duplicated.
2. If there are ECMP routes, enabling on one backbone VLAN is desirable for any UDP relay service.
3. If 802.1Q is configured on multiple switches, UDP relay service only needs to be enabled on one
switch.

OS7000 does not support VRID 0. OmniCore does
Workaround: Do not use VRID 0 on the OmniCore other devices when running VRRP with the OS7000.
PR 62272
Exceeding the multicast software routing processing limits can introduce instability to VRRP master to
backup communications resulting in VRRP switching between master and backup states frequently on the
OS7000.
Workaround: Reduce the amount of IP multicast traffic running through the affected NI.
