Usually when setting up the switches and etherchannels it is said as part of the requirement : Make sure that ONLY VLAN 1 can carry untagged frames. What is meant by that exactly ? Does it have to do with the fact that VLAN1 is by default the native van ?
and how do we determine when to use a router in FR as a hub. I.e. in the beginning configurations we often have 4 way FR network with R2 as the hub (For example) and R4, R5 and R6 using R2 as the go-to point (502 for .2, .4 , .6. and self-map through any chosen DLCI). But here in the later labs i don't see any of that, and the DLCI's actually map straight to each other and we have separate ones for each router to router pvc. Vol2, Lab 4, task 3.1 How do these configurations prevent from sending data over the mentioned DLCI's ? (We have a full mesh of of DLCI's but R4 and R6 are only supposed to have OSPF traffic passed to R2, not each other). Is it maybe because of the configuration in task 2.1, where we do not specify the broadcast argument between R4 and R6 (that puzzled me). Any help would be appreciated as always, sorry for spamming the list so much!
