Folks,I had some very basic questions on the way hashing takes place on Cisco switches connected to each other over a port channel.Considering that 2 links are used between the switch, namely port Gi 0/1 and Gi 0/2.1) By default I understand that thi...
Folks,I have attached a topology which we are looking to achieve for some routing design. Below are the questions: 1) We need that the P-2-P link between both the Data Center is used only by the traffic betweens the Data Centers.2) Consider a scenari...
Folks,I seen a network with some wired behavior when BGP is enabled with another ISP. TIll now that network was having BGP enabled with a single Provider(Provider A) who had 2 links coming in and at the back end it was a blended solution, one of thos...
I am trying to understand what does the "data" license exactly do on the Cisco 3900 series router. What I understood is that the data license supports "MPLS.ATM. Multiprotocol support".Question is is a do not have this license will I not be able to r...
I came across a requirement to achieve some routing preference using BGP with the service provider on the Internet.We are having 2 Internet links from different service providers, Provider-A and Provider-B and both running BGP with us. The BGP is con...
Thanks for the detailed explanation Joseph.I got the concept of hashing but just to take an example if the source IP is 1.1.1.1 and the destination IP is 2.2.2.2 then would the hashing be like take the last 3 bits from 1.1.1."1" and 2.2.2."2"? In thi...
Hi Chris,This started to sink in to some extent So it looks like how to divide the bits is decided by the switch.In my case I have a port channel which shows Load values of 56 and A9 on one of the port channels(each port channel shows different valu...
Guess I am not able to understand this well...The bits should be as follows:1) 0002) 0013) 0104) 0115) 1006) 1017) 110 111 These should be divided evenly like, 000, 011 and 110 to the first port channel, correct? i.e. 1st, 4th and 8th combination in...
Local Pref would still be taken into account by the entire AS i.e. all the routers in the iBGP, correct?Assume I modify the Local Pref at the Data Center Provider routers. These routers would still see the iBGP neighbor advertising the better path to...
Consider, that I manipulated local preference on the provider 2 router in DC2 so that it sees the best route to DC1 via the provider 1 router and not the P2P router.Now once the traffic reaches that provider 1 router routes will still go to the P-2-P...
