Description: The first IP Address of the router IP Address range.
What is cienaCesMcastIgmpSnoopRouterRangeStartIpAddr?
This is the starting address of a configured IP range used to identify which source addresses on this service should be trusted as legitimate multicast routers, working alongside the end-of-range object to filter router traffic. An admin locking down which upstream devices are allowed to act as the multicast router for this service, to prevent a rogue or misconfigured device from injecting bogus router queries, sets this start address as the low bound of the accepted range. A value of 192.0.2.1 combined with a matching end address would define exactly which addresses the device treats as legitimate router sources.
