What is VTP in Cisco?
VLAN Trunk (or Trunking) Protocol (VTP) is a Cisco proprietary Layer 2 messaging protocol that reduces administrative chores in a switched network by managing the addition, deletion, and renaming of VLANs on a network-wide basis. It permits configuration of VLANs on a single VTP server, with the VLAN distributed through all switches in the domain. To enable this, VTP carries VLAN information to all the switches in the VTP domain, using advertisements sent over Inter-Switch Link (ISL), 802.1q, IEEE 802.10 or LAN Emulation (LANE) trunks. VTP traffic is sent over the management VLAN (VLAN1), so all VLAN trunks must be configured to pass VLAN1.
What is Cisco Resilient Ethernet Protocol?
Cisco Resilient Ethernet Protocol (REP) is a new technology implemented on Cisco Carrier Ethernet switches and intelligent service edge routers. It extends network resiliency across Cisco IP Next-Generation Network (NGN) Carrier Ethernet Design. Requiring no hardware upgrades, REP is designed to provide network and application convergence within 50 ms. In some scenarios, the network convergence times may increase to within 250 ms, but a 250-ms convergence time is still expected to have limited or no discernible effect on most network applications. REP is a segment protocol that integrates easily into existing Carrier Ethernet networks. It is not intended to replace STP, but allows network architects to limit the scope of STP domains. Since Cisco REP can also notify STP about potential topology changes, it allows for interoperability with STP. Ideally, REP can be positioned as a migration strategy from legacy spanning tree domains.
What is SVI in a switch?
