Hello, everyone.My book states the following regarding multiple links between routers:When a router has multiple links toward another LDP router, the same transport address must be advertised on all the parallel links that use the same label space.My...

Hello, everyone.I understand that, by default, if we don't set a transport address for LDP sessions manually, they will use their router ID's value as their transport address. So if a device's RID is 1.1.1.1, it will try to use 1.1.1.1 as its transpo...

Hello, everyoneIOS-XR documentation for LDP states the following when it comes to determining the LDP router ID:I have the following loopbacks configured:When I enable MPLS LDP, it picks 1.1.1.1 as the RID:Why is this the case? I haven't configured a...

Hello, everyoneI understand that LDP discovers neighbors and what IP addresses to use in order to build the TCP session between the two LSRs by using multicast LDP hellos that are sent to 224.0.0.2, UDP 646.From what I've seen, the hello interval is ...

Hello, everyone.I understand that normal IP MTU commands represent how big a layer 3 packet can be without having to fragment it.The MPLS MTU command represents how big a labelled packet can be (the IP packet + the MPLS labels). If we set the MPLS MT...

Hello!I suppose you're right. However, if the receiving router believed the different transport addresses to be different peers, shouldn't it build a TCP connection to each one, then?I've been thinking, each hello has the LSR's ID in it, so it knows ...

Hello!I don't think the statement in the book indicates that. Luc De Ghein states the following:If a prefix is reachable via a mix of labeled and unlabeled (IP) paths, Cisco IOS does not consider the unlabeled paths for load-balancing labeled packets...

Hello @Giuseppe Larosa,My goal was to send multicast traffic from AS 100 to AS 200 which succeeded even if the RPs peered directly and not with anyone in AS 300. PIM was enabled everywhere and once R4 sent a JOIN, the tree was built across AS 300. AS...

Hello M02@rt37 Thank you for the response. My book states that non-DFs can forward packets from the link toward downstream receivers. So shouldn't R1's G2 interface also be amongst the incoming interfaces? Since it therefore techically is one of the ...

Hello!Yes, they are in CML. I wasn't sure whether I misconfigured something or whether it's just the emulator's limitation.David
