Seniors,
I was doing a lab & got stuck as I could not get reachibilty to my Backbone
Routes (BB2 & BB3)
In spite of knowing the complete practice Lab i could not complete it.
Scenario.
R6 --- Trunk to bb1 & bb2
BB1 - vlan 10
bb2 - vlan 20
Configuration I did.
R6
Gig 0/1
no ip address
duplex full
speed 100
int gig0/1.1
encapsulation dot1q 10
ip add .X.X.X>X/24
int gig0/1.2
encapsulation dot1q 20
ip add X.X.X>X/24
the port Gig 0/1 is connected to Switch 2 -- Fas 0/6
configuration
int fas 0/6
switch port trunk encapsulation dot1q
switch port mode trunk
switch port allowed vlan 10,20
BB1& bb2 -- connected to SW2 & SW3 fas 0/0
*SW2*
conf t
int fas 0/0
switchport mode access
switchport access vlan 10
*SW3*
int fas 0/0
switchport mode access
switch port access vlan 20
Please guide me .. I fail to understand .. I have done this many times but
some how this time It was not working.. I checked my configuration at least
10 times.
Apart from that the trunk links were up between all the switches & ether
channel was up .
Later I released that the BB2 router CPU utilization reached 99% in no
time..
I don't have any other configuration saved.. But the configuration I have
posted is the same that I have done while configuring.
Senior please guide me, Thanks for all the support given so far.
Awaiting your reply.
Regards
Sam
