Configuring N3024 Switch as Redundant

Dear All,

Hi, I just get Dell N3024 as a Core Switch and X1026 as Access.

I try to create topology like this :

VLAN 10 : 10.10.10.xxx/24

VLAN 20 : 20.20.20.xxx/24

VLAN 30 : 30.30.30.xxx/24

VLAN 40 : 40.40.40.xxx/24

Just trying using interface vlan each Switch, 

Switch A :

ip routing

interface VLAN 10

ip address 10.10.10.1 /24

Interface VLAN 20

ip address 20.20.20.1 /24

Interface VLAN 30

ip address 30.30.30.1 /24

Interface port 2

switchport mode trunk

Switch B :

ip routing

interface VLAN 10

ip address 10.10.10.2 /24

Interface VLAN 20

ip address 20.20.20.2 /24

Interface VLAN 30

ip address 30.30.30.2 /24

I think my config is far from done and not best practice...

My question is, what should I configure on each DELL N3024, so all VLAN can connected to Internet? (can create assumption for the ip of Sonic Wall port)

Please kindly need your help.

Thanks before.

    Dear Daniel,

    Thanks for your answer.

    I forgot to mention that SonicWall series is 2600...

    Can SonicWall 2600 is each port  have the same subnet? (port 1 and port 2 have subnet ex : 50.50.50.0/24)

    If I have the IP of SonicWall that directly connect to Switch A is : 50.50.50.2

    So should I do this?

    Switch A:

    Interface port 1 :

    no switchport

    ip addr 50.50.50.1

    exit

    Switch B:

    Interface port 1 

    no switchport

    ???

    ???

    1. For Static Routing, should I do like this :?

     

    Switch A :

    ip default-gateway 50.50.50.2

    ip route 0.0.0.0 0.0.0.0 50.50.50.2 253



    Switch B:

    ip default-gateway ???

    ip route 0.0.0.0 0.0.0.0 ???  253

    2. I'm using VRRP with master & backup mode...

    Should I register all VLAN with each VLAN for each VLAN?

    for Ex :

    Switch A

    ip routing

    ip vrrp

    interface VLAN 10

    ip addr 10.10.10.1 /24

    vrrp 10

    vrrp 10 ip 10.10.10.254

    vrrp 10 priority 200

    vrrp 10 preempt

    vrrp 10 track interface vlan 50 (Should I use this?)

    vrrp 10 track ip route 50.50.50.0/24 (or I use this?)

    exit

    Switch B

    ip routing

    ip vrrp

    interface VLAN 10

    ip addr 10.10.10.2 /24

    vrrp 10

    vrrp 10 ip 10.10.10.254

    vrrp 10 priority 200

    vrrp 10 preempt

    exit

    Please need your answer and review for this.

    If you all have suggestion/opinion please dont mind.

    Thanks before

    Thanks Daniel 

    Btw,I have another question,

    1. What should I configure to port which is directly connect to SonicWall?

    switchport mode access 

    switchport access vlan 1

    or 

    switchport mode trunk

    switchport trunk allowed vlan all

    2. for VRRP configuration :

    vrrp 10 track interface vlan 50

    vrrp 10 track ip route 50.50.50.0/24

    Should I use this example configuration on each switch or just one switch (Master Switch)?

    3. Oh yes, when I'm using VRRP, I get this picture :

    Why it have Backup and Master on one switch? Whats the problem? Is it OK?

    Thanks again Daniel

    Hi Daniel,

    Here the output :

    From SwitchA (Master) : here

    and

    From SwitchB (BackUp) : here

    Thanks before.

    Hi Daniel,

    Thanks again.

    Yes, I still using VLAN 1 to pass traffic, still dont try the another one.

    For SonicWall, can X0 and X1 the same VLAN?

    ex: (All with  vrrp 10 ip 50.50.50.254)

    X0 = LAN = 50.50.50.2

    X1 = LAN = 50.50.50.2

    Switch A:

    Interface 1 = Access mode for VLAN 50

    VLAN 50 = 50.50.50.253

    ip route 0.0.0.0 0.0.0.0 50.50.50.2

     

    Switch B:

    Interface 1 = Access mode for VLAN 50

    Int VLAN 50 = 50.50.50.254

    ip route 0.0.0.0 0.0.0.0 50.50.50.2

    or

    X0 = LAN = 50.50.50.2

    X1 = LA;N = 50.50.50.3

    Switch A :

    Interface 1 = Access mode for VLAN 50

    VLAN 50 = 50.50.50.252

    ip route 0.0.0.0 0.0.0.0 50.50.50.2

     

    Switch B:

    Interface 1 = Access mode for VLAN 50

    Int VLAN 50 = 50.50.50.253

    ip route 0.0.0.0 0.0.0.0 50.50.50.3

    Thanks before

    Hi Daniel,

    So from your answer, the Gateway on SonicWall (X0 & X1) can be the same VLAN but different IP address.

    And CMIIW for the conclusion for this topology :

     

    SONICWALL

    X0 : 10.10.10.1/24

    X1 : 10.10.10.2/24

    SWITCH A

    ip routing

    ip vrrp

    interface port 2

    switchport mode trunk

    Interface VLAN 10

    ip address 10.10.10.252 /24

    vrrp 10

    vrrp 10 ip 10.10.10.254

    vrrp 10 priority 200

    vrrp 10 preempt

    vrrp 10 track interface vlan 10

    vrrp 10 track ip route 10.10.10.0/24 

    exit

    ip route 0.0.0.0 0.0.0.0 10.10.10.1

    SWITCH B

    ip routing

    ip vrrp

    interface port 2

    switchport mode trunk

    Interface VLAN 10

    ip address 10.10.10.253 /24

    vrrp 10

    vrrp 10 ip 10.10.10.254

    vrrp 10 priority 200

    vrrp 10 preempt 

    exit

    ip route 0.0.0.0 0.0.0.0 10.10.10.2

    NOTE : Each VLAN (20,30) must be set to VRRP one each switch just like VLAN 10 but with the same subnet of their IP.

    VLAN 20 : 20.20.20.xxx/24

    VLAN 30 : 30.30.30.xxx/24

    Thanks before

    Thanks a lot Daniel,

    How about the VRRP when Im using different VLAN on each switch that direct to firewall (VLAN 50 & VLAN 51)?

    Should I use  different track ip route on VRRP or only on master?

    ip route 0.0.0.0 0.0.0.0 50.50.50.1

    vrrp 50 ip 50.50.50.254

    vrrp 50 priority 200

    vrrp 50 track interface vlan 50 

    vrrp 50 track ip route 50.50.50.0/24

    vrrp 50 preempt

     

    and

     

    ip route 0.0.0.0 0.0.0.0 50.50.51.1

    vrrp 51 ip 50.50.51.254

    vrrp 51 priority 195

    vrrp 51 track interface vlan 51 

    vrrp 51 track ip route 50.50.51.0/24

    vrrp 51 preempt

     

    And for the link that from/to storage & server, should I use spanning-tree portfast?
