But this broadcast problem is caused by ARP, right? Are there any other ways to fill up the MAC table without using ARP?
View ArticleComment by Noob_Guy on Do DSLAM and OLT function like a switch?
Actually I mean can they communicate without using router. Forget the real world setup. If this is a lab setup, is communication possible? That's what I'm asking.
View ArticleComment by Noob_Guy on Why do we need ATM if SONET/SDH can carry IP directly?
Oh ok. What about telephony. Why does voice telephony need ATM if it can ride directly on SONET?

Let's say for example there is an Ethernet switch, and there are four PCs connected to this switch. PC1 and PC2 are communicating with each other, and at the same time PC3 and PC4 are also...
View ArticleDo routers understand transport protocol?
We are taught about the difference between hubs, switches, and routers. A hub is a layer 1 device, it only knows layer 1 and doesn't care about layer 2 and above. Similarly, a switch is a layer 2...
View ArticleIs datagram switching only possible with routers?
So datagram switching is when packets from same original message travel different paths from source to destination. This cannot happen with switches because switches would just run STP thus disallowing...

When talking about VLANs I often see examples like this:VLAN 10 - 10.0.10.0/24VLAN 20 - 10.0.20.0/24Different subnets yet different VLANs. I understand this is a must if we want communication between...
View ArticleHow to advertise a classless network in RIPv2?
In OSPF and EIGRP we can advertise specific networks only using wildcard masks. For example, if a router has networks 10.0.10.0/24 and 10.0.20.0/24, we can choose to advertise only 10.0.10.0/24 by...
