Layer 3 LAG on vRR 7750 SR-12
In this lab I wanted to try if LAG (Link Aggregation Group) will work GNS3.
Very basic configuration:
On R1 as following
A:R1>config>port# info
----------------------------------------------
ethernet
no autonegotiate
exit
no shutdown
----------------------------------------------
A:R1>config>lag# info
----------------------------------------------
port 1/1/1
no shutdown
----------------------------------------------
A:R1>config>router>if# info
----------------------------------------------

port lag-12
no shutdown
----------------------------------------------
A:R1>config>router>isis# info
----------------------------------------------
level-capability level-1
area-id 49.01
interface "system"
no shutdown
exit
interface "toR2"
interface-type point-to-point
no shutdown
exit
no shutdown
----------------------------------------------On R2 as following
A:R2>config>port# info
----------------------------------------------
ethernet
no autonegotiate
exit
no shutdown
----------------------------------------------
A:R2>config>lag# info
----------------------------------------------
port 1/1/1
no shutdown
----------------------------------------------
A:R2>config>router>if# info
----------------------------------------------
address 12.12.12.2/30
port lag-12
no shutdown
----------------------------------------------

area-id 49.01
interface "system"
no shutdown
exit
interface "toR1"
interface-type point-to-point
no shutdown
exit
no shutdown

=============================================================================Anything I missed here or the emulator just really does not work well? any thought, comment, etc? thanks!
I will test LAG as layer 2 some other time.
