Segment Routing (SR) is new way of routing which is flexible and scalable. SR is based on source routing and allows to create a path by combining segments. The source chooses a path and encodes it in the packet header as an ordered list of segments. Each segment is identified by the segment ID (SID) […]

IP SLA is a feature that enables a Cisco router or a switch to simulate specific types of traffic useful for analysis. Cisco IOS IP SLAs performs active monitoring by generating and analyzing traffic to measure performance either between Cisco IOS devices or from a Cisco IOS device to a remote IP device such as […]
IGMP (Internet Group Management Protocol) is communication protocol used by receivers/hosts to signal their adjacent/local Multicast routers that they are interested in multicast traffic for a particular group. IGMP is Host to router signalling protocol for Mulitcasting. IGMP has protocol number “2” and runs on Top of Network layer i.e. at Transport layer. IGMP protocol […]
