Hi, hope you're all well.
I'm moving towards VRRP and OSPF for the routing between each site (4/5 sites). Currently we're routing off some old school Firewalls with L3 VPN routing between 3 sites via the ISP Connectivity. As the budget won't stretch to get some new core switches and firewalls I'm going to use the 3750's.
I just want to check for site A, that I set the internal NiC on the firewall to say 192.168.100.2, I route the traffic statically as the Next hop from the SVI vlans? Or do I put it in the subnet I planned for the VPLS and let the routing after the firewall carry out the NATting I intend to use on the firewall?
I'm going to paraphrase this to save on your reading time.
VPLS subnet: 10.10.10.0/26
Site A (WAN Site):
3750-1 int gi 1/0/1: ip address 10.10.10.2/26, ip ospf priority 10, vrrp ip 10.10.10.1/26
3750-2 int gi 1/0/1: ip address 10.10.10.3/26, ip ospf priority 5, vrrp ip 10.10.10.1/26
router ospf 15, log-adjacency-changes, network 192.168.100.0 0.0.0.255 area 0, network 192.168.110.0 0.0.0.255 area 0, network 192.168.120.0 0.0.0.255 area 0
Local vlan SVI's: vlan100 - 192.168.100.0/24, vlan - 110 192.168.110.0/24, vlan 120 - 192.168.120.0/24
Help, advise, recommendations more than welcome.
Thanks in advance
