887VA Internal IP Configuration

Hi,

 

Hope you can help.

 

I am installing a 877VA and connecting to 3750 Core and need to access video streams over VPN to 3 internal inter-routed VLANS...

 

VLAN1 = 192.168.153.1\24

VLAN2 = 192.168.150.254\24

VLAN3 = 192.168.151.254\24

 

I have my 877 working over VPN but i'm stuck on how best access resources on my internal network above? As it stands I can only connect to my test subnet of 10.10.10.0 255.255.255.248. I have included initial config below...

Re: 887VA Internal IP Configuration

Hello esprit1987,

the first step is to create a shared IP subnet between the 877VA and the C3750 core switch.

The best thing is to add a new Vlan like vlan 50 on both devices

 

877VA

config t

vlan 50

to-core

exit

interface vlan 50

ip address 10.10.50.1 255.255.255.0

no shut

 

interface fastethernet3

description to switch 3750 port gi1/0/X

switchport

switchport mode access

switchport access vlan 50

!

Then you need to add three static routes to internal networks with nexthop C3750:Vlan50 IP address

 

ip route 192.168.153.0 255.255.255.0 10.10.50.2

ip route 192.168.150.0 255.255.255.0 10.10.50.2

ip route 192.168.151.0 255.255.255.0 10.10.50.2

 

on the switch C3750 you do the following

 

config t

vlan 50

name tocore

exit

interface vlan 50

desc to router 877VA

ip address 10.10.50.2 255.255.255.0

no shut

 

int gi1/0/12

description to router 877VA:fas3

switchport

switchport mode access

switchport access vlan 50

no shut

!

On C3750 you will have a default route pointing to 877VA address in Vlan 50

ip route 0.0.0.0 0.0.0.0 10.10.50.1

 

At this point you should be able to ping from network 10.10.10.1 to each internal networks

 

B) VPN extension

 

You are using the IPSEC VPN as a remote access the current ACL should be modified to access also the internal networks added in section a) as static routes

 

p access-list extended vpn_resources
permit ip 10.10.10.0 0.0.0.255 any

! lines to be added if needed:

permit ip 192.168.153.0. 0.0.0.255 any

permit ip 192.168.150.0 0.0.0.255 any

permit ip 192.168.151.0 0.0.0.255 any

 

note: I'm not sure these additional lines are needed

 

Hope to help

Giuseppe

Re: 887VA Internal IP Configuration

Hello esprit1987,

connect two unused FastE ports on 877VA with a crossover LAN cable this should make one port to be STP Designated port for Vlan1 and the other to be blocked and SVI Vlan1 should come up/up (remove spanning-tree portfast on both ports  before doing this to avoid the possible creation of a bridging loop!!!)

Note: a straight cable may work if FE ports support auto cross connect MDI-X.

 

 

Hope to help

Re: 887VA Internal IP Configuration

Hello,

 

I assume the 3750 is doing the inter-Vlan routing ? Can the Vlans on the 3750 reach the 10.10.10.0/29 address space defined on the router ?

One thing: you cannot have Vlan1 on both the router and the switch, in two different address spaces.

 

Best to post the full configuration of your 3750 as well...

Re: 887VA Internal IP Configuration

Thanks for your prompt reply.

 

Thats correct my 3750 is doing the inter VLAN routing. Unfortunatly I couldn't ping anything outside of my VPN or visa versa. I did try creating a VLAN 10 Interface to solve this issue of VLAN1 conflict but no joy. Must me something I'm missing.

 

Here is my 3750 config...

Re: 887VA Internal IP Configuration

Hello,

 

while I was working on the specifics, it looks like Giuseppe already provided the answer. Either way, I'll post what I have come up with anyway, sorry if I am being redundant.

I have summarized your 192.168.x.x networks into one statement, if you don't want that, you need to specify each subnet in one separate line. I have also added the internal networks connected to your switch to the NAT access list, so they can access the Internet (optional of course, if you don't want that).

 

Changes/additions are marked in bold:

Re: 887VA Internal IP Configuration

Hello esprit1987,

the first step is to create a shared IP subnet between the 877VA and the C3750 core switch.

The best thing is to add a new Vlan like vlan 50 on both devices

 

877VA

config t

vlan 50

to-core

exit

interface vlan 50

ip address 10.10.50.1 255.255.255.0

no shut

 

interface fastethernet3

description to switch 3750 port gi1/0/X

switchport

switchport mode access

switchport access vlan 50

!

Then you need to add three static routes to internal networks with nexthop C3750:Vlan50 IP address

 

ip route 192.168.153.0 255.255.255.0 10.10.50.2

ip route 192.168.150.0 255.255.255.0 10.10.50.2

ip route 192.168.151.0 255.255.255.0 10.10.50.2

 

on the switch C3750 you do the following

 

config t

vlan 50

name tocore

exit

interface vlan 50

desc to router 877VA

ip address 10.10.50.2 255.255.255.0

no shut

 

int gi1/0/12

description to router 877VA:fas3

switchport

switchport mode access

switchport access vlan 50

no shut

!

On C3750 you will have a default route pointing to 877VA address in Vlan 50

ip route 0.0.0.0 0.0.0.0 10.10.50.1

 

At this point you should be able to ping from network 10.10.10.1 to each internal networks

 

B) VPN extension

 

You are using the IPSEC VPN as a remote access the current ACL should be modified to access also the internal networks added in section a) as static routes

 

p access-list extended vpn_resources
permit ip 10.10.10.0 0.0.0.255 any

! lines to be added if needed:

permit ip 192.168.153.0. 0.0.0.255 any

permit ip 192.168.150.0 0.0.0.255 any

permit ip 192.168.151.0 0.0.0.255 any

 

note: I'm not sure these additional lines are needed

 

Hope to help

Giuseppe

Re: 887VA Internal IP Configuration

Looks positive, much appreciated.
I'll give this ago and I will up date with progress...

Re: 887VA Internal IP Configuration

Hi Both,

I think we're nearly there with the config provided, however, I cannot ping across from 10.10.10.0 from the VPN connection because now I am using FE3 as VLAN 50 to the 3750, VLAN1 interface is down. How do I keep this interface UP when nothing is plugged into a VLAN1 port?

Re: 887VA Internal IP Configuration

Hello esprit1987,

connect two unused FastE ports on 877VA with a crossover LAN cable this should make one port to be STP Designated port for Vlan1 and the other to be blocked and SVI Vlan1 should come up/up (remove spanning-tree portfast on both ports  before doing this to avoid the possible creation of a bridging loop!!!)

Note: a straight cable may work if FE ports support auto cross connect MDI-X.

 

 

Hope to help

Giuseppe
