What’s Changed in Release 21.1R2
General Routing
-
Changes in contextEngineID for SNMPv3 INFORMS (PTX Series, QFX Series, ACX Series, EX Series, MX Series, and SRX Series)— Now the contextEngineID of SNMPv3 INFORMS is set to the local engine-id of Junos devices. In earlier releases, the contextEngineID of SNMPv3 INFORMS was set to remote engine-id.
Interfaces and Chassis
-
Blocking duplicate IP detection in the same routing instance (All Junos platforms)—Junos will no longer accept duplicate IPs between different logical interfaces in the same routing instance. Refer to the table mentioned in the topic inet (interfaces). When you try to configure same IP on two logical interfaces inside same routing instance, the commit will be blocked with the error displayed as shown below:
[edit] user@host# set interfaces ge-0/0/1 unit 0 family inet address 2.2.2.2/24 [edit] user@host# commit commit complete [edit] user@host# set interfaces ge-0/0/2 unit 0 family inet address 2.2.2.2/24 [edit] user@host# commit [edit interfaces ge-0/0/2 unit 0 family inet] 'address 2.2.2.2/24' identical local address found on rt_inst [default], intfs [ge-0/0/2.0 and ge-0/0/1.0], family [inet]. error: configuration check-out failed
