LDP vs RSVP - Cisco Learning Network
LDP is designed to be highly extensible, using TLV triplets to be able to transport multiple additional fields in the future and warrantee the compatibility with previous versions via ignoring the unknown new fields. LDP is highly flexible, as supports local and remote neighbors (using targeted LDP sessions).
MPLS without LDP - Cisco Learning Network
If you want to avoid LDP, Segment Routing is what people look at today: dspdrivers made an excellent blog about segment routing a little while back: Introduction to Segment Routing Expand Post Like Liked Unlike Reply
Link Layer Discovery Protocol (LLDP) - Cisco Learning Network
Link Layer Discovery Protocol (LLDP) Link Layer Discovery Protocol (LLDP) is a vendor independent link layer protocol used by network devices for advertising their identity, capabilities to neighbors on a LAN segment. LACP specified in IEEE 802.1AB. One-way protocol with periodic retransmissions out each port (30 sec default). LLDP Frame Format.
VPLS - BGP vs LDP Signaling - Cisco Learning Network
Thanks. It is far simpler to operate BGP signalled VPLS. For an LDP signalled VPLS instance, you have to go to your PE's, and configure each of the other PE's that this service terminates on. If the service needs to be extended to a new PE for some reason, then you need to go back around all the existing PEs, and add new configuration to them.
LDP to Segment Routing Migration 1 - Cisco Learning Network
The status now is that both LDP and SR are working together inside the network and the communication is still in place , what next to be done is to instruct the routers to prefer SR label assignments/bindings over the already used ones generated by LDP. router isis 1. address-family ipv4 unicast. segment-routing mpls sr-prefer
Difference between LDP discovery holdtime and peer holdtime?
Here the guy says that Discovery hold timer is used during session establishment but session hold timer used once the TCP connection is established. I know that by default the Discovery hold timer is 15 sec whereas session hold timer is 180 seconds. So I simulated a case where 1 router was missing LDP hellos from its neighbor and it took 15 ...
MPLS LDP IGP SYNC in IOS XR? - Cisco Learning Network
Sure enough, fired up a new topology and as soon as I enabled mpls on the interfaces, XR automatically enables igp sync and what's worst is that you can't turn it off, meaning you can't turn disable even if you issue the command [disable], Has anyone seen otherwise?
mpls ldp sesstion protection - Cisco Learning Network
R2(config)#mpls ldp session protection duration 30. this means "TO ME" that if the physical link between R2 and R3 is down, R2 is going to leveraging from the IGP and going to receive 3/32 from another route and is going to maintain this subnet into his LFIB even if the physical link between R2 and R3 goes down: R2(config)#interface ...
MPLS LDP and Router ID /32 - Cisco Learning Network
This results in a broken data plane through the MPLS core. To fix this situation, you have 2 solutions: A - Change the subnet mask to /32: interface loopback 0. ip address 10.1.1.1 255.255.255.255. ip ospf 1 area 0. B - Change the OSPF network type of the loopback interface: interface loopback 0.
