I have a task to compare different approaches to implement InterVLAN routing in campus network. Google suggests only Cisco technologies for such query. But what I need is also other companies solutions (like Dell, HP etc), cost of the implementations, pros and cons.

We have an available 3845 with a VWIC2-2MFT-T1/E1 card. We are supposed to be getting 2-T1 lines from Verizon. I have a spare 3750 L3 switch for the core and 6 access switches.
The desktop team has asked me to set up multicast in our network with building PC's as they will be deploying a few hundred of them starting in two weeks. We currently do not have multicast set up, and the only experience I have with it was during my certification studies, so I have a lot to catch up on quick. They will be sending the build traffic from a single server. The network environment is simple: a 3750 stack as the router/distribution layer and mainly 3550's as access. The PC's that they will be imaging will be on one VLAN that is already designated for PXE builds. This VLAN is across multiple switches. Is it possible to just enable the multicast features on a single VLAN? I have been reading around but not finding much other that very in-depth Cisco papers.

I have attached some diagram here, 2911 Router configured as a zone based firewall and it works fine. I need to put ASA 5510 as an internal Firewall in to the existing network. So I need to hand-over the NATing configuration from IOS FW to ASA 5510 , are there any special configs here? I have done this but it's not working, If i bypass IOS ZB FW and ASA directly connect to internet Its works fine, If NAT configurations keep in IOS ZB FW then it works fine.

I have a major problem regarding implementing IP Multicast in an ADSL network. The diagram of our network is attached. In every Access Network , there is only IP DSLAMs which are connected via Metro ethernet links ( L2 links) to the main site. So there is no Router or Layer 3 Link to the main site. In the main site there is an Aggregator router which is an PPPOE server which terminates subscriber's PPPOE sessions. All the Access networks and subscribers are just connected to one Aggregator and they use that one as PPPOE server. It is an Cisco 3845 Router. Then the Aggregator is connected to Core network and behind the Core network is an Streaming server which streams in Multicast. IP Multicast Routing is configured in Spars-Dense mode in all routers in Core network and also the Aggregator and it is working properly. So the sucscribers are able to join the multicast stream and the very last router in the path toward the subscribers( which is the Aggregator) does the Multicast replications.
There are two problems we faced:
1- Since all the subscribers from different Access Network use the same Aggregator in the central site as PPPOE Server, all the connection are terminated on that router. The goal is to use the uplink bandwidth of the Access networks to the central site more efficiently and if e.g 20 subscribers watches the same channel, it just consumes as the amount of one channel due to doing IP Multicast.Now the problem is that when for example 2 subscribers of the same Access Network (in the same POP site) connect to the same stream, the amount of bandwidth used between the central site and the Access network is double. It happens because the aggregator activates IGMP on every virtual-access lines for every PPPOE subscribers who wants to joint the stream. So it can not recognized these two subscribers are from the same Access network. Therefore, the result is that although it is doing Multicast, it does not save the bandwidth because it activates IGMP group on every subscriber's virtual access line for his PPPOE connection. So is there any solution to this problem? Something came to my mind that we need to implement a separate aggregator for every Access network which means that we have to place a router for every access site and it will be expensive for us. But I think in that case every local aggregator can do IP Multicat routing and it saves the bandwidth definitely. Any better solution that may solve our problem using the same topology?
2- Another problem is that when the subscriber's CPE are configured in bridge mode and subscribers set-up a PPPOE connection on their PCs, they are able to join the multicast stream properly. But when they put their CPE in router mode and have their ADSL modems as PPPOE client, they are not able to join the Multicast stream. i.e the ADSL modem is doing NAT and routing and it connects to PPPOE server using username/password credentials. I also tried a feature in ADSL modems called "IGMP support" when I wanted to create the WAN settings. But it did not work. I am not sure but I think that we need "IGMP Proxy" feature on subscriber's CPE.
upgrading our small office network. We currently have about 75 employees with probably 125 devices on the network. I'd like to create about 10 vlans for the different departments and then configure intervlan routing as needed. Currently we have all unmanaged switches and it's just a huge broadcast storm on the network. We are upgrading our Cisco 800 router to an ASA5505 sec. Plus license. I need some recommendations on switches. Of course, this needs to be done as cheap as possible.... Is there a way to use the ASA to configure all the vlans and intervlan routing and access lists and use a cheaper switch to provide the access layer to hosts?

I am using a 3750 as a default gateway for multiple Vlans on a few 2960 switches. The trunk lines are configured and working and I have assigned ip addresses to each of the Vlan interfaces on the 3750. My issue is that I can only ping the ip address on the Vlan interface of the 3750 if I have a working computer plugged directly into the Vlan on the 3750. I only have 3 vlans on the 3750 that have hosts directly connected (vlans 2, 10 and 40) the other vlans ( 20 and 70) don't have any clients plugged into them on the 3750 but the hosts reside on 2 different 2960s that connect via trunk ports. How do I keep the vlan interface on the 3750 switch pingable when I don't have hosts directly connected in that vlan on the 3750? (yes, I have enabled ip routing on the 3750)

I have 3560 with attached 3 networks, 172.16.1.0/24 172.16.2.0/24 and 172.16.4.0/24, all of them have a vlan interface, 172.16.1.254, 172.16.2.254, and 172.16.4.254, I have enabled intervlan routing with command ip routing and they have route beetwen each other. Now I want to create PBR and let them go to the internet from different gateways.
so i did 3 access list:
access-list 20 permit 172.16.1.0 0.0.0.255
access-list 10 permit 172.16.2.0 0.0.0.255
access-list 30 permit 172.16.4.0 0.0.0.255
and 3 pbr
route-map supnet permit 20 match ip address 10 set ip next-hop 172.16.2.3
route-map blade permit 20 match ip address 30 set ip next-hop 172.16.4.250
route-map main permit 20 match ip address 20 set ip next-hop 172.16.1.4
attached them to corresponding vlan interfaces and everything ok they have different gateways to internet but now I dont have routing beetwen them?

We currently have VLAN 10 as the untagged VLAN for Gateway 1, and VLAN30 as a tagged vlan for Gateway 2. Since both gateways are requiring untagged traffic, I need to make sure all ingress traffic from Gateway 2 gets tagged as VLAN30, while all egress traffic gets untagged.
The tricky part is they must come over the same port so I can't just tag it that way. I get the feeling this will require some static routes or VLAN Interfaces on the switch, but I'm not sure where to start.

The server team has asked me to implement jumbo frames on a single VLAN, the one they use for v motion. We have two pairs of 5548s, each pair running VPC for most connections. I am aware of many postings that describe how to enable jumbo frames globally, like this:
policy-map type network-qos jumbo
class type network-qos class-default
[code].....
I am not clear how I can extend this principle to one VLAN only.
Also, I am aware of a posting [URL], that shows some pitfalls of implementing jumbo frames in a VPC configuration. Pretty well all my connections are VPC, including all the FEXes, which are all dual-homed. In many cases, the VPC extends through to the servers so that the servers run port.channels across two FEXes. I am unclear whether the pitfalls are still valid, or whether I have to wait until my next maintenance slot (6 months away) to implement jumbo frames. Can jumbo frames be implement safely on the fly? How does enabling jumbo frames fit in with "conf sync" mode?

What do I need to change or setup in the switch or asa configuration in order for the other vlans to access the Internet through the ASA.
