HiIm looking at setting up a sites resilience using dual connections to two routers running BGP. If the two links are not equal i.e. the primary link that all traffic routes over in a normal situation is 100Mbps but the back link that will be used sh...
Hiim struggling to understand how VLAN dot1q tags are handled internaly on the switch. When a frame enters an access port in say vlan 5 is it tagged ingress on the switch so the switch knows what vlan it belongs to. what about with a dot1q when a fra...
HiDoes anyone know if you can have a EoMPLS VPN where one end is terminated to a dot1q subinterface and the other end is port based such as below.Router1int fa0/0.1 enc dot1q 1 native!int fa0/0.2 enc dot1q 2 xconnect 10.10.10.102 2 enc mpls!Router2in...
HiIf you are connecting 2 networks together via an ethernet switched dot1q trunk is there anyway to translate the vlans over it. i.e. your network is using vlans 10 and 20 but the network you are connecting to are using vlans 100 and 200. Any advice ...
HiOn our network we use 6500/4500 and 2851 routers. On some of our connections we have large output drops "Total output drops: x" counter.Does anyone know how often this counter is incremented is it for every drop or say 1 in 100 i.e. is it limited i...
HiThis makes sense the core device is a 4507 and the remote router is a 2851 all running FIFO. I guess I was lucky in the lab that BGP didnt fail. Will do some further lab testing and look into other queueing methods if required.RegardsKev
hithat makes sense so the tag is stripped and has no internal signifficance it is only used to decide what part of the mac-add-table to look at.RegardsKev
HiSorry the bit iam confused about is when a tagged frame is received on a dot1q trunk is the tag retained for the switch to make internal forwarding decisions and also when a un-tagged frame is received on an access port is it tagged again for inter...
HiThanks for the replies, it looks as though on the above link that the "Ethernet to VLAN over AToM (Bridged): Example " example will do just what I need so will test this one out. Do you know what the "interworking ethernet" does under the pseudowir...
