Version 2 broadcast and multicast
Step1: Configure authentication on interface1 of Router A
interface1 on Router A: (Default version or version 1 compatible)
Send: Version 1
Receive: Version 1
Version 2 broadcast and multicast with authentication
interface2 on Router B: (Default version or version 1 compatible)
Send: Version 1
Receive: Version 1
Version 2 broadcast and multicast
The packet exchange between Router A and Router B is still version 1, so as above
configuration there will be no impact on packet flow.
Step2: Configure same authentication on interface2 of Router B
interface1 on Router A: (Default version or version 1 compatible)
Send: Version 1
Receive: Version 1
Version 2 broadcast and multicast with authentication
interface2 on Router B: (Default version or version 1 compatible)
Send: Version 1
Receive: Version 1
Version 2 broadcast and multicast with authentication
The packet exchange between Router A and Router B is still version 1, so as above
configuration there will be no impact on packet flow.
Step3: Configure version 2 broadcast on interface1 of Router A
interface1 on Router A: (Version 2 broadcast)
Send: Version 2 broadcast with authentication
Receive: Version 1
Version 2 broadcast and multicast with authentication
interface2 on Router B: (Default version or version 1 compatible)
Send: Version 1
Receive: Version 1
Version 2 broadcast and multicast with authentication
The packet exchange from Router A to Router B is version 2 broadcast with authentication.
Authentication was already configured on Router B also, so Router B will accept the packets
from Router A. The exchange from Router B to Router A is still version 1 (no
authentication). Router A is allowed to receive version 1 packets even in version 2 broadcast
mode.
Step4: Configure version 2 broadcast on interface2 of Router B
interface1 on Router A: (Version 2 broadcast)
Send: Version 2 broadcast with authentication
Receive: Version 1
Version 2 broadcast and multicast with authentication
interface2 on Router B: (Version 2 broadcast)
Send: Version 2 broadcast with authentication
Receive: Version 1
Version 2 broadcast and multicast with authentication
