Subject: Re: HUGE STP VLAN problem
Hello.
After consulting with the colleague, here is the situation.
What you are trying to do is called a MUXED UNI, required for EoMPLS
(basically saving you money for ES20 linecard)
How it is done is that you do a
interface TenGigabitEthernet2/1
switchport
switchport trunk encapsulation dot1q
switchport trunk allowed vlan 100-200
switchport mode trunk
interface TenGigabitEthernet2/1.150
encapsulation dot1Q 150
So, don't forget allowed vlan list.
BUT, this feature is available only in the latest SRC release, as far as I
know.
So if you are not configuring MUXED UNI for EoMPLS, do not configure this.
Use vlans and trunks instead, because creating routed interface creates an
internal vlan anyway.
I.e.
interface TenGigabitEthernet2/1.150
encapsulation dot1Q 150
ip add 10.0.150.1 255.255.255.0
interface TenGigabitEthernet2/1.151
encapsulation dot1Q 151
ip add 10.0.151.1 255.255.255.0
is exactly same as
interface TenGigabitEthernet2/1
switch mode trunk
int vlan 150
ip add 10.0.150.1 255.255.255.0
int vlan 151
ip add 10.0.151.1 255.255.255.0
but first one will not work :)
