Multicast Routing Overview. IP Multicast is a technology that allows one-to-many and many-to-many distribution of data on the Internet. Senders send their data to a multicast IP destination address, and receives express an interest in receiving traffic destined for such an address.

Hi, I really don't understand why GET VPN uses a tunnel mode for multicast packets : Examples for an @multicast = 239.0.0.37 : 1 ) here a GET VPN packet : |239.0.0.37|ESP|239.0.0.37|transport layer|Payload| : This mean, it uses the tunnel mode of IPsec (two IP headers). 2 ) here a packet that i im RFC 7988 IR Tunnels in MVPN October 2016 As with any type of P2MP tree, each node of an IR P-tunnel holds "multicast state" for the P-tunnel. That is, each node knows the identity of its parent node on the tree, and each node knows the identities of its child nodes on the tree.

Nov 21, 2019 · Like @NolanHerring said the MX cannot route multicast traffic, so you cannot forward it over the AutoVPN. But yes, if you had another external device that could do multicast routing you could GRE tunnel it between two endpoints through the AutoVPN tunnel. This could be either a L2 or L3 GRE depending on how you wanted to do it. Feb 20, 2018 · Multicast Optimizations with Route Types 6,7,8 • Route Type 6 (Selective Multicast) • To efficiently forward multicast traffic over an EVPN network; only PEs interested in the traffic should receive it. • Route Type 7,8 (IGMP Proxy) • Reduce Bum state just like Proxy ARP. IGMP reports are summarized and propagated to BGP peers. Now my office can reach the Voip server without a problem, but my voip server can't do autoprovisioning on the 192.168.1.0 range (by which phones are found with Multicast) Is it possible to somehow multicast also on the 192.168.1.0 range ? The IGMP proxy feature sounds like what I need, but I have no clue on howto configure it….

multicast traffic, there are multiple destination systems per. multicast group. So some system or person will need to coordinate. among all multicast groups to select an SPI or SPIs on behalf of each. multicast group and then communicate the group's IPsec information to. all of the legitimate members of that multicast group via mechanisms. not

The IP unicast packet surrounding the multicast packet creates a “tunnel” that the IPSec tunnel encrypts and transports to the authenticated device at the receiving end. The resulting architecture is GRE over IP Security (IPSec), which is the most widely chosen VPN architecture for securely transporting multicast with advantages in Examples: Configuring Unicast Tunnels If you want to view the stream at multiple concurrent locations, then you would set the AVN’s destination IP address to a valid Multicast IP address (224.0.0.0 – 239.255.255.255). Note that while the Multicast IP address range is from 224.0.0.0 – 239.255.255.255, the first octet (224.xxx.xxx.xxx) is generally reserved for administration. Multicast routing is very different than unicast routing. Multicast is a form of broadcast, and like broadcast, it will not normally cross a layer-3 device, e.g. router. To overcome this, you use IGMP and PIM to route multicast. You should also be aware that many tunnels cannot transport multicast. You need a GRE tunnel. – Ron Maupin May 25
