Does RIP v2 support VLSM?
RIPv2 – classless – sends subnet mask in the routing updates, thus supporting VLSM and CIDR. Like RIPv1, RIPv2 is a distance vector routing protocol.
How do you summarize an IP address?
The summary route number is represented by the first IP address in the block, followed by a slash, followed by the number of common bits. As Figure 1-17 illustrates, the first 22 bits of the IP addresses from 172.16. 12.0 through 172.16. 15.255 are the same.
What does IP summary address RIP do?
The ip summary-address rip routerconfiguration command causes the router to summarize a given set of routes learned via RIP Version 2 or redistributed into RIP Version 2. Host routes are especially applicable for summarization.
Does RIP support VLSM?
RIPv1 does not support VLSM (Variable Length Subnet Masking). RIPv1 support maximum metric (hop count) value of 15. Any router farther than 15 hops away is considered as unreachable.
What is the OSPF multicast address?
224.0.0.5
OSPF uses multicast functions when interfaces are attached to broadcast networks, such as Ethernet. For all OSPF routers, these interfaces are joined to multicast address 224.0. 0.5. Only the packets that are destined for the 224.0.
What is a summary address?
A summary route, sometimes called a manual summary route, is a route advertisement that lists a single route. The range of addresses that match that single route includes the same addresses in multiple other subnets in a router’s routing table.
What is auto summarization in RIP?
Auto summarization is a feature which allows Routing Information Protocol (RIP) to summarize its routes to their classful networks automatically.
What is summarization in EIGRP?
Auto summarization is a feature which allows Enhanced Interior Gateway Routing Protocol (EIGRP) to summarize its routes to their classful networks automatically. For example, consider we are planning to use eight subnets of class B default network 172.16. 0.0/16, subnetted using a three-bit subnetting as shown below.
What routing protocols are RIP and RIPv2?
RIP and RIPv2 are distance vector routing protocols. OSPF and IS-IS are link state.
How are configuring RIPng and RIPv2 different?
RIPng works basically in the same manner as RIP v2 with one notable exception. RIPng can only run on IPv6 networks. Additionally, it uses different IP address lengths, RIPng uses 128-bit IP addresses (to accommodate IPv6 128 bit addressing), compared with RIPv2’s 32-bit addresses.
What is RIPv2 (RIPv2)?
The Cisco implementation of the Routing Information Protocol (RIP) Version 2 (RIPv2) supports authentication, key management, route summarization, classless interdomain routing (CIDR), and variable- length subnet masks (VLSMs). By default, the software receives RIP Version 1 (RIPv1) and RIPv2 packets, but sends only RIPv1 packets.
What is the best route to summarize in VLSM?
Route Summarization with VLSM. Therefore, the best summary route is 172.16.168.0/21. You can summarize addresses when the number of addresses is a power of two. If the number of addresses is not a power of two, you can divide the addresses into groups and summarize the groups separately.
What is the default authentication in a RIPv2 packet?
Plain-text authentication is the default authentication in every RIPv2 packet. Do not use plain text authentication in RIP packets for security purposes, because the unencrypted authentication key is sent in every RIPv2 packet.
How do I check if RIPv2 is working on my router?
Once you have fully configured RIPv2, execute the show ip route command to check the tables created on the routers and check the Routes. Route records in R2 are as follows. You can see how routing updates are performed by applying the debug ip rip command to verify the routing protocol on Cisco Routers.
