Has anyone else seen an excessive amount of ESP probes being sent to every public IP address . Makes me think there's a new exploit out. Check logs on the routers. Haven't ever in past 20 years seen this much probing using ESP packets. Just a head...
I have a network running ospfv3 with ipv4 address family for many years with a combination of IOS and XR and Juniper and Arista devices and I tried to add a nexus 9k to it and there's no address-family ipv4 in ospfv3.. what in the heck? Am I missing ...
Anyone know if there's a way to get this working on nexus equipment? https://www.juniper.net/documentation/en_US/release-independent/solutions/topics/task/configuration/centrally-routed-overlay-cloud-dc-configuring.html https://eos.arista.com/centr...
This documentation seems wrong, and doesn't work. Am I missing something or does the documentation need to be fixed.Talking about :Configuration Centralized VRF Route-Leaking - Shared Internet with Custom VRFhttps://www.cisco.com/c/en/us/td/docs/swit...
I am having an issue with route leaking between VRFs in EVPN getting blackholed. I swear I had this working in the lab the other day and now it's not.Example setup is 2 leaf one spine. Leaf A vrf Test1L2VNI 1000 L3VNI 1001 Leaf Bvrf Test2L2VNI 2000...
1. VRF is a LOCAL concept to each switch so the names/numbers of the VRF on different switches have no relation. It works because it's like any other interface and the neighbor is reachable.2. Usually the management link is used, or a dedicated lay...
I made another post in this form explaining this , not sure what the link is at the moment. The Vlan ID is only local per VTEP device, so the limitation on the number of vlans is only local to that device. Now I suppose if you have 4000 customers a...
The need to tunnel routed traffic is so the other nodes know what VRF to put it in on the other side. If there was only one vrf, there's no need to tunnel , although some do anyway to avoid blowing up routing tables on devices that don't need it. If...
This is missing the point entirely.. it was never that the route couldn't be sent to the VRF , it was two 'bugs', plus a third issue.. 1. The readvertise like XR has wasn't there so it couldn't be done this way (and now this command is in NXOS , not ...
What code versions are you running? 3m cable requires FEC on host port, 2m doesn't. 3m FEC has to be BASE-R (FC-FEC) (i think this is CL74 on the 9300 side and FC-FEC on nexus, 9300 network modules are weird, don't seem to auto negotiate anything)
