Under normal circumstances, when a untagged frame reaches the end of the trunk link, the frame will be assumed to belong to the native vlan of the trunk link. The 802.1Q tag will be removed and the frame will be forwarded out to those ports in the na...
Please help to advise on the ports to configure guard root so that Sw1 can remain as the Root, in the event the priorities of Sw2, Sw3, Sw4 or Sw5 are reduced.For both examples, please assume all else are equal (priority, link cost, etc).For Example ...
Extracted from course materials."VIDs are associated with only those frames that traverse a trunk link. When a frame enters or exits the switch on an access link, no VID is present. The ASIC on the switch port assigns the VID to a frame as it is plac...
I understand that when a host receives an arp request packet, and the IP address to be resolved is not for this host, then the arp request packet will be discarded. The arp cache will not be updated since a host will update its ARP cache, only if the...
In conclusion, am I right to say that 1) Frame entering an access port is NOT tagged with any Vlan ID. That in turn implies that any frame exiting access ports do not have any Vlan ID.2) Frame entering a trunk link will be tagged with the Vlan ID tha...
>> Coming to your topology. R3 learns the route to 11.2 from R1(inter area i.e. via area 0) & R2(intra area i.e. via area 1 from serial interface 1/1). Thus from above concept of preferred routes, R3 prefers the intra area path (i.e. directly to R2 v...
I have attached the network diagram (proper diagram this time )Since 172.31.11.2 is in Area 0, R3's preferred route should be via R1 to reach 172.31.11.2? If that is so, then the route from R4 to 172.31.11.2 should be R4-(cost1)->R3 f0/0-(cost64)->...
But there is no LAN interface connection between R4 and R2. In my diagram above, R4's FastEthernet0/0 (10.1.1.3/24) is connected to R3 FastEthernet0/0 (10.1.1.1/24). So for R4 to reach the frame relay cloud, it has to pass through R3 since R4 is conn...
R1 should be the hub while R2 and R3 should be the spokes. Logically, R1's Serial1/0.1 is connected to R2's Serial 1/0.1 _and_ R3's Serial1/0.1 through the frame relay cloud (The three interfaces are in Area 0). The only direct connection between R2 ...
