Hi ,
In my environment we have 7613 series router having SONET and Gigabit interfaces on it , we have done subinterfacing on SONET for connecting multiple WAN connections.One of it's gigabit interface i.e G0/1 which is connected to my core switch of 6500 series on it's G0/2 through which all internal traffic move out to Internet.The scenario is given in figure 1.
I need to clear the concept regarding the implementation of FWSM in Transparent mode in 7613 router and movement of traffic through FWSM.
1.How internal traffic which is moving out from G0/1 of 7613 to G0/2 of 6500 series for accessing internet be able to move to FWSM in this manner.
(7613 Router) G0/1 ----Inside Int.(FWSM) ---- Outside Int. (FWSM) ---G0/2 (6500 Switch).
2.I think that we can configure intially like this for moving traffic from G0/1 (7613) ----> Inside Int.(FWSM)
a.We put Interface G0/1 of 7613 and Inside interface of FWSM in same VLAN for e.g VLAN 10.
b.Assign Management IP address on BVI Interface of FWSM for management purpose for e.g 192.168.10.10.
3.Then I need to know how traffic moves from outside interface (FWSM) ----> G 0 /2 of (6500 Switch)
As I have studied that FWSM is connected to MSFC through SVI Interface. So suppose we create a SVI Interface for VLAN 20 and assign IP address 192.168.10.20 and also put Outside Interface of FWSM in VLAN 20 as can be seen from figure 2.
4.Now I have a doubt that how traffic move from MSFC to G0/2 of 6500 Switch because on MSFC we have switching processor for L3 routing purpose.
So it means that for moving traffic from MSFC to G0/2 we need to create another interface SVI2 on MSFC for new VLAN suppose VLAN 30 and give IP address 192.168.30.10 and also assign new IP address to G0/2 of 6500 for e. 192.168.30.20.
So please let me know that will this configuration work and things are missing or not correct in above mentioned discussion.
Thanks
