I can understand the answer but I have my doubts if the process is right. The first criterion for installing a route into routing table is the prefix length and the next one is AD. So in this case you have these regarding the same exact prefix:
- One static route with AD 252
- One BGP route width AD 20
I cannot find any reason that the first one is selected when both routes exist in the database. The one with lower AD should be preferred.

Hello, is there the necessary routing information for the switch to return traffic to the PCs/Servers? Another possible cause could be an ACL. Enable debug ip icmp at the switch and check if the pings from the PCs arrive. If yes then check the routing for the return path. Let us know about the results.

Hello, regarding the scenario depicted you have to make the fa 0/1 ip dhcp snooping trust.All the other links are assumed as untrust. The dhcp snooping has nothing to do with authenticating users and permit specific IPs that has its in binding table. If you want this you should enable the ip source feature. The dhcp snooping simply not permit DHCP offers messages from untrusted ports so that it eliminates the possibility for a rogue DHCP server in your network. In addition to that it saves the bindings done through the DHCP offer messages it sees. This has no meaning if you do not enable the ip source feaure (except you know the IP addresses given in each port/pc. The switch do not authenticate the messages based on this binding table. For example if there is a PC on switch port gi 0/5 that has been assigned the IP 1.1.1.1/24 and you then connect another pc with a static IP of 1.1.1.10/24, this PC will communicate and have access normally. Now, if your clients have already connected and assigned IP addresses and then you enable the ip dhcp snooping feature then the snooping binding table will start populated when clients re-ask dhcp server for IP address. Keep in mind that DHCP Snooping feuture do not inspect actual packet but only DHCP packets. I hope I helped.

In order to do a vlan rewrite either in ingress packet or egress packets you have to include the rewrite command under the service instance.

If you use nbar then you will achieve what you want. You must then match the traffic you want with policy map and limit the available bandwidth.

If you use subinterfaces for the l2vpn you should use the rewrite ingress command. If not then you should not. The concept is same as in IOS.

Try to find a program in order to monitor your network. You can try a free version of netflow in order to check the normal traffic pattern of your network.
