  • Question 62:

    Avaya recommends using RSMLT edge in place of VRRP with Backup Master, when available what are two valid reasons for using RSMLT edge? (Choose two)

    A. the VRRP hold down timer cannot be set high enough to update the complete routing table when Layer 2 access requirements are high.
    B. RSMLT edge provides support for application where more than 255 redundant default gateways (VRRP limit) need to be provided.
