rcVrrpOperHMACMD5Key
Module: RAPID-CITY
OID (symbolic): RAPID-CITY::rcVrrpOperHMACMD5Key
OID (numeric): 1.3.6.1.4.1.2272.1.73.1.1.2.1.12
Node type: OBJECT-TYPE
Type: OCTET STRING
Access: read-write
Description: The Authentication Key. If the virtual router's 'Authorization Type' is 'ipAuthenticationHeader', and the key length is shorter than 16 octets, the agent will left adjust and zero fill to 16 octets.
When read, rcVrrpOperHMACMD5Key always returns an Octet String of length zero.
What is rcVrrpOperHMACMD5Key?
This OID stores a 16-byte security key used for authentication in virtual router redundancy (a technology that lets multiple routers share a single virtual IP address). Setting this key enables cryptographic verification that VRRP messages come from trusted routers and haven't been tampered with. A network operator would configure this key once when setting up redundant routers to ensure only authorized devices can participate in the failover group.
