Multicast Listener Discovery Protocol

RFC 2710 defines specifications for the Multicast Listener Discovery (MLD) protocol. MLD is derived from IGMPv2 and is designed for IPv6. The operation of MLD is similar to IGMPv2. The major differences between IGMPv2 and MLD are as follows:

Point-to-Point Protocol

The two most popular Layer 2 protocols used on point-to-point links are High-Level Data Link Control (HDLC) and Point-to-Point Protocol (PPP). The ISO standard for the much older HDLC does not include a Type field, so the Cisco HDLC implementation adds a Cisco-proprietary 2-byte Type field to sup...

Advanced Security Concepts

A wealth of security concepts have been covered in the previous chapters; now, you are ready to look at some of the techniques that are used to secure areas of your network that are vulnerable to attacks, in particular the demilitarized zone (DMZ).

IEEE 802.1Q Protocol

The IEEE 802.1Q protocol also can carry VLAN associations over trunk links. However, this frame-identification method is standardized, allowing VLAN trunks to exist and operate between equipment from multiple vendors. In particular, the IEEE 802.1Q standard defines an architecture for VLAN use, serv...
