What problem does AnyCast RP solves?Having a single active rendezvous point (RP) is a single point of failure. Anycast RP allows two or more rendezvous points (RPs) to share the load for source registration and the ability to act as hot backup routers for each other. Multicast Source Discovery

In the previous articles, we have discussed about PIM Dense Mode and PIM Sparse Mode. Both protocols use IGMPv2 and known as Any Source Multicast (ASM). You can check out both articles below: Juniper Multicast PIM Dense ModeMulticast OverviewIP has three fundamental types of addresses: unicast, broadcast, and multicast. A

PIM Sparse mode uses an 'explicit join' approach whereas PIM Dense mode uses 'implicit join' approach. With PIM Sparse mode, only network segments with active receivers that have explicitly requested the data will receive the traffic. ‌‌‌‌ PIM sparse mode distributes information about active sources by forwarding data packets on the

Multicast OverviewIP has three fundamental types of addresses: unicast, broadcast, and multicast. A unicast address is used to send a packet to a single destination. A broadcast address is used to send a packet to an entire local subnet. A multicast address is used to send a datagram to a

In the previous post, we discussed about the Type-4 and Type-5 LSAs. This article focuses on Stub and NSSA areas. I highly recommend you to read my previous post here: OSPF Type-4 & Type-5 LSAs - JunosIn the previous posts, we discussed about the Type-1, Type-2 and Type-3 LSAs. This

In the previous posts, we discussed about the Type-1, Type-2 and Type-3 LSAs. This article focuses on Type-4 and Type-5  LSAs. This is the fourth post in the Junos OSPF series. Let's look at the Type-5 LSA first. Type-5 External LSAs are originated by an ASBR and flooded  by ABRs

In the previous posts, we discussed about Type-1, Type-2 and Type-3 LSAs. This article focuses on OSPF Route summarization. I highly recommend you to read my previous posts here: Juniper OSPF Configuration ExampleIn this blog post, I will go through Junos Single area OSPF configuration andverification using Juniper vLAB Sandbox.

In the previous post, we discussed about the single-area OSPF and Type-1, Type-2 LSAs. This article focuses on multi-area OSPF and Type-3 Summary LSAs. I highly recommend you to read my previous post here: Juniper OSPF Configuration ExampleIn this blog post, I will go through Junos Single area OSPF configuration

In this blog post, I will go through Junos Single area OSPF configuration and verification using Juniper vLAB Sandbox. Interfaces and OSPF configurations are already done for us, so we can jump straight into exploring and understanding various Junos OSPF features.   Kudos to Juniper for providing such great resources.
