HSRP with IP default gateway

[miank]

Hi Fellows,

I am working on below topology , can anyone help me out to ping from my PCs (in VLAN 10,and 20) to another switch's Virtual IPs in diff VLAns. 

[Julio E. Moisa]

Thank you, I have fixed the priorities on the 4th swiches.

SW1
Priority 125    (active)

SW2
Priority 120     (standby)

SW3
Priority 115     (listen)

SW4
Priority 100    (listen)

For both VLANs, Im going to check the IP plan. I will keep you posted.

:-)

Hi

The command:

standby 1 and 2 should be the same on the 4 switches. It represents the virtual IP.

Thanks !

I have below IP Plan

  Signaling VLAN 106

For servers connectivity: 10.200.44.144/29

For switches internal connectivity: 10.200.44.152/29

 IP Breakup for switches internal connectivity:

10.200.44.152/29	10.200.44.152
	10.200.44.153	Virtual IP (Gateway for myswitches)
	10.200.44.154	Physical IP on telcom Sw1
	10.200.44.155	Physical IP on telcom Sw2
	10.200.44.156	Virtual IP (Gateway for telcom)
	10.200.44.157	Physical IP on myswitches Sw1
	10.200.44.158	Physical IP on myswitches Sw2
	10.200.44.159

 OAM VLAN 128

For servers connectivity: 10.200.44.224/27

For switches internal connectivity: 10.200.45.0/29

IP Breakup for switches internal connectivity:

10.200.45.0/29	10.200.45.0
	10.200.45.1	Virtual IP (Gateway for myswitches)
	10.200.45.2	Physical IP on telecom Sw1
	10.200.45.3	Physical IP on telecom Sw2
	10.200.45.4	Virtual IP (Gateway for telecom)
	10.200.45.5	Physical IP on myswitches Sw1
	10.200.45.6	Physical IP on  myswitches Sw2
	10.200.45.7

Thank you

I found the ip default-gateway is different so you need to align them to be the same on the 4 switches. 

Im going to share with you the the fixed config. I would like to recommend use a routing protocol on the 4 layer 3 switches.

Hi Julio,

Sorry for late reply...

Thanks a lot for your help. i have configured 3750 switches as per fixed configuration. works well. Thanks !

Thanks everyone else !!!

Have a great day.

Hi Cofee & Julio,

I have attached Packet tracer files for SW1,SW2,SW3 and SW4 and also below PCs IP settings. i just be able to ping from SW3 to SW1 & SW2 gateways but not able to ping from SW1 to SW3 & SW4 gateways. Also cannot ping from VLAN 10 to SW1, SW2, SW3 and SW4 gateways.

Thanks !

PC1 VLAN 10

IP 10.200.44.147

subnet 255.255.255.248

GW 10.200.44.145

PC2 VLAN 20

IP 10.200.44.227

SM 255.255.255.224

GW 10.200.44.225

[Julio E. Moisa]

Thank you very much, could you please share the packet tracer file as well. Im going to verify the shared txt files. 

At first sight I have see you are not using priorities to indicate who will be the active HSRP switch (the higher will be selected as active). If you dont configure that it will take the default value (100). If all the HSRP are with 100 it can generate a problem.

Why will you create multiple HSRP for the same VLAN????

SW1- VLAN 106- SW2--HSRP IP -10.200.44.156

SW1- VLAN 128 -SW2--HSRP IP- 10.200.45.4

then you are creating HSRP

SW1 - VLAN 106- SW3--HSRP IP - 10.200.44.153

SW1- VLAN 128 -SW2--HSRP IP-10.200.45.1

Why do you need to extend same vlan 106 and vlan 128 towards SW3 and SW4. Does not make sense. Never seen this kind of design. Curious how this will work.
