People,
Good afternoon,
We have a curious situation in a client's environment.
It has a M7i router with 2 IQ2E (4 GE) PICs.
It wants one of its PICs plugged into a L2 switch (802.1Q Trunk Mode)
and the another one plugged (via 1 giga of 4 ports only) to another L2
switch.
M7i
/ \
S1 S2
Both Giga ports are simpled configured like:
nterfaces {
ge-0/0/0 {
vlan-tagging;
nterfaces {
ge-0/1/0 {
vlan-tagging;
L2 Trunk Ethernet only without L3 configuration.
It is possible to get flow information about the encapsulated vlans
(10,20,30,40, etc) inside the trunk traffic ? ... without configuring ip
(4 or 6) or creating vlan interfaces ?
It is possible to get cflow working in a L2 way ?
Does anyone has configured it before using JUNIPER ? Can you send or
point to me some samples of configuration ?
Thanks a lot,
Giuliano
