Hello, I’m doing a simple Lab to understand the LOOP caused by configuring different Site-Of-Origins (SoO) with BGP in Multihomed sites.The following scheme demonstrates what I did : 3 PEs with MPLS implemented between them. PE-1 is connected to CE...
Hello Everyone,
I see that most of LANs and DCs which contain Po in their switches and use Source/Dest IPs or MACs addresses result in a static loadbalacing of flow in links.
I mean that many times we see that a link (or more) is saturated and cont...
Hi All,
What's the default method of Spanning-tree Calculation of Cost (Pathcost Method Long 32 bits or Pathcost Method Short 16 bits) in Cisco Nexus Switches ?
As I understand, if we have > 1 G links in our Architectures (LANs, DCs, ...) and nowad...
Hi all,
So the question is simple as the title indicates
I use OSPF between 4 Leafs and 2 Spines.
Multicast trafic is well implemented (the spines will be acting as Anycast RP ..).
Config of VxLAN (VNI, Int NVE, ...) done.
Is it obligatory to u...
I have 2 Nexus 5Ks connected with an OSPF Link implemented. The MTU value is 1500 by default.
The neighborship is OK.
Now, I have modified the MTU value of the 2 extremities of the OSPF Link to 9216. The Neighborship is KO and the state is stucking...
Thnks for reply !
I think that Spanning-tree always calculates the best path to a destination based on Cost (not in hop counts). And the issue here is in relation with Cost : with the method Short it uses 16 bits in the field of this cost and here ...
Yes I have exactly this Log message !
%KERN-3-SYSTEM_MSG: packet_sendmsg: packet size 9246 > MTU 9230 - kernel
But in the workaround it says that the known fixed release is 5.1(3)N1(1) while I'm now with 7.0(7)N1(1) version and it is recommanded by...
Thank you Paul and Kumar for your responses.
So, I understand that the best way is to inject the LAN Networks into OSPF (with passive interface command) in order to avoid Type 5 LSAs, isn't it ?
If this correct, could you explian please what is t...
