The JUNOS software implementation of RIPng is similar to RIPv2. However, RIPng is a distinct routing protocol from RIPv2 and differs in a few aspects from the older version of RIP. Aside from the general architectural limitations of RIPng as stated at the beginning of this chapter the following additional differences are specific to JunOS in comparison to RIPv2:

RIPng does not need to implement authentication on packets.

• There is no support for multiple instances of RIPng.
• There is no support for RIPng routing table groups.
