In terms of "work the host has to do", I would say that there is no difference between all the methods EXCEPT for manual, they are all automatic and decided by the upstream devices.Manual requires someone to actually configure the IPs, but all other ...

Would you say the TLOC is present in the underlay or overlay?I think it is both, as the "next hop" for prefixes in an overlay VPN will resolve to a TLOC, and the TLOC contains the public and private address required to route the packet, in the underl...

Hello, 2 questions about multicast:1) When configuring PIM passive, can you configure it on the source router, destination router, and intermediate nodes? I believe you can.2) I believe IGMP is only required to be configured on the destination device...

HelloI was advertising an aggregate address of of 10.31.0.0/16 I have 2 other network statements that match both a directly connected and OSPF learned prefix (10.31.0.0/30 & 10.31.32.0/24).Using a different device on-site, I advertised 10.31.129.0/24...

Hello, I was wondering if there were minimum pool requirements for both the LAN Automation and IP Handoff pools. LAN AutomationFor LAN Automation, I believe the formula for calculating the number of IPs (when using 2 interfaces per device) required i...

I don't have access to my lab right now, but what is the next hop in the overlay, to a prefix on a remote site in the same VPN? (assuming no route filtering)

Thanks Peter and all for commenting on this, much appreciated!So on some examples I saw for SSM, IGMPv3 had been enabled on a completely different router and interface which happened to be the source interface, just "ip igmp version 3" - see https://...

I have just tested and in fact I believe this is the wrong way around for GRT -> VRF.I believe the vrf on the NAT statement should be used if the source is in that VRF, not the destination.Also would probably help more if it explained the routing req...

I think I know what the problem is now, thanks. I have a NO_TRANSIT route-map with (^$) as an as-path. This aggregate then breached that rule so wasn't advertised.I have tested and confirmed once I added in 10.31.0.0/16 separately, it all worked, als...

So I answered my own question in the end. I removed "as-set" and the aggregate was advertised once again.
