How does the IP forwarding works ?

Hi Aron,

 

 

Thanks for the reply.

 

 

I modified my lab, now I have separate VLANs for internal, external and management, now my lab is broken if I access the virtual IP from another subnet other than the external VLAN.

 

 

I configured the default route, and now the routing table look like this:

 

 

[root@test-f5:Active] config bigpipe route show

 

ROUTE default inet

 

| VLAN External static

 

ROUTE 10.0.0.0/24

 

| VLAN External connected

 

ROUTE 127.1.1.0/24

 

| VLAN tmm0 connected

 

ROUTE 192.168.1.0/24

 

| VLAN Internal connected

 

ROUTE fe80::/64

 

| VLAN tmm0 connected

 

ROUTE fe80::%vlan4093/64

 

| VLAN External connected

 

ROUTE fe80::%vlan4094/64

 

| VLAN Internal connected

 

ROUTE ff02::/64

 

| VLAN tmm0 auto

 

ROUTE ff02::%vlan4093/64

 

| VLAN External auto

 

ROUTE ff02::%vlan4094/64

 

| VLAN Internal auto

 

 

 

if it is a Cisco router, I expect the default route should have a next-hop IP, so when it forwards the traffic, it knows where to forward to, in F5 routing table, it looks there is no next hop, only the VLAN, how can the F5 box knows the mac-address to encap the packet ?

 

 

Sorry if this question is too obvious, I am digging F5 from scratch, and have no background what so ever : -0
