VSP 8600 VRRP IDs

Customer’s experiencing error when creating 9th VRRP instance.

Error: maximum number of VRRP entries exceeded

Release notes for version 6.2 explains that it is possible to create more than eight VRRP instances but have to re-use the first eight VRRP IDs chosen previously.

“Because there is a hardware limitation of using only eight MAC addresses for VRRP, the number of VRIDs is also limited to eight. You can use any eight values for VRIDs between 1 and 255. However, once you choose the eight VRID values, you must reuse the same eight values across all VLANs on the device.”

Note: Tested with Firefox 65 (64 bit) and Internet Explorer 11 against ERS 5.3.9.011 with HTTPS. Uses SHA-256 with RSA encryption. Chrome version 72 (64 bit) fails with ‘bad format’ error and may need to use an older release (ERR_SSL_SERVER_CERT_BAD_FORMAT).
