Hello!
I am working on final year networking project of my degree. In here i have planned a highly available network according to Cisco hierarchical (three-layer) inter-networking model by using Cisco packet tracer. Two Multi-layer switches (Cisco 3560-24 PS) of distribution layer have been used for redundancy which has been used for creating VLANS, DHCP, Routing and etc. Here below my network topology.
I have planned to issue IPV6 address from DHCP pool by using Multi -layer switch into relevant VLANS. But there is not a knowledge how to create DHCP IPV6 pool in Multi-Layer switch. And also, I need to know a DHCP redundancy. In here if one switch will downgrade there will not be issued DHCP IPs to the client.
I have read about a DHCP redundancy article in IPV4. In here some of them had suggested to exclude half of IP address in one switch and that IPs were used for other switch DHCP pool. Excluded IPs in other switch will be used in this switch for preventing collision. But I thinks that it’s not possible for my scenario because there may be used different IP addresses for VLANS.
On the other hand, as i plan there can be created same IPV6 pool in both Multi-Layer switches and the virtual IP (using GLBP) can be used as a Default Gateway for DHCP pool. Will it be possible? Is there any solutions to overcome for this problem?
I would like to be grateful if any one help for me. Thank you!
