Hello,
I am having trouble understanding the direction in which the load-balancing algorithm is applied in a switching scenario.
Consider two switches S1 and S2 connect together via a port-channel.
S1 is on the left and S2 is on the right.
On S1 if...
Hello,
I have been unable to find a succinct answer to this question so I thought I would ask on the official Cisco support forums.
If two switches are trunked together with 802.1Q and the native VLAN is tagged on one side with "(config)#vlan dot1q...
Hi,
I have an access layer switch with two trunks facing two seperate routers which are connected together via a L3 link and L2 trunk (this is a mixed End-to-End VLAN and Local VLAN scenario).
I would like to use HSRP to have a virtual gateway for t...
Hi,
I would like to know from those who have deployed AS-Path prepending configuration in a BGP multihoming scenario.
Does this involve any significant disruption in connectivity or is it seamless like adjusting local preference and then resetting ...
Hi,
If I am multihoming with two providers with two seperate routers and running iBGP between them - will both my routers have to store two seperate copies of the routing table thus consuming twice the TCAM space? So roughly over 1 million routes?
Hi Jon,
I think my issue may arise with my understanding of STP - I posted a question a while ago concerning Local VLANs and created a lab in packet tracer. I could see that the uplinks were not blocked due to the V topology created. (No loop as the ...
Thanks for confirmation so are you saying it would be wise to switch to GLBP to get round the L2 loop issue (ie, ARP request broadcast looping) for Local VLANs in HSRP?
Hi Jon,
Thanks for that I too updated mine yes I can see how that could be an issue if the Active HSRP interface was live but the uplink itself on the switched failed.
That aside however would there be away to bring up both HSRP Active/Standby pair...
Hi Jon,
Thanks for the response I thought so although I have observed the following:
The standby interface stays in Init mode, only when it is allowed on the trunk does the interface then switch to Standby. I have then tested failover and this works...
Hi Masoud,
Yes PVST is configured and root brige on R1 is lowest with R2 as the secondary root bridge.
A trunk has been configured between the routers to allow end-to-end VLAN communication.
There is a L3 etherchannel (interface vlan 90) to pass t...
