IS-IS Features in the JUNOS Software
The Juniper Networks JUNOS Software supports authentication for IS-IS protocol exchanges (HMAC-MD5 or simple authentication), link-state packets, sequence-number packets (complete sequence number PDU [CSNP] and partial sequence number PDU [PSNP]), and IS-IS hello packets (IIH).
The JUNOS Software supports the advertisement of MPLS label-switched paths into IS-IS.
