I am just looking for confirmation
Do you require an isolated trunk link when using dot1q-tunnel or do you just need to ensure the VLAN is allowed on the respective trunk? For example |R1| 0/1 ----- 0/1 |CAT1| 0/21 0/22 ============ 0/21 0/22 |CAT2| 0/2 ---- 0/0 |R2| You want R1 and R2 to see each other as CDP neighbors. CAT1 ____ interface 0/1 switchport access vlan 999 switchport mode dot1q-tunnel l2protocol-tunnel cdp no cdp enable vlan 10,20,30,40,999 CAT2 ____ interface 0/2 switchport access vlan 999 switchport mode dot1q-tunnel l2protocol-tunnel cdp no cdp enable vlan 10,20,30,40,999 For the trunks 21 and 22 (not running etherchannel) I could run all VLANs across both 21 and 22 I could run VLANS 10,20,30,40 on 21 and 999 on 22 Are there any issues with either option ? _______________________________________________ For more information regarding industry leading CCIE Lab training, please visit www.ipexpert.com
