adding switches to the core
I currently have two 3560 L3 switches running HSRP and etherchannel between them. These core switches are configured with separate vlans for different traffic such as

I''m fighting all kind of STP and HSRP glitches, and I''m guessing that my connections between the core switches are partially to blame. Bottom line: what is the preferred way to connect
For this case, I have 2 core switches and only 2 available hosts are provided on the /30. Therefore I cannot IP both switches on this range along with the router and vlan interface IP.
If your network consists of several internal routable subnets and the devices/systems on those subnets communicate regularly and do not warrant being separated by firewalls, the gateway
Selecting between core, aggregation, and access switches is not only technical — it''s strategic. Once you know what your network needs, choosing the right type of switch will optimize
This L3 engine is provided by the Nexus Core Switch (which must have an appropriate Layer 3 image and license). On the Core Switch, for each Layer 2 vlan we will configure an SVI (Switch Virtual
I have 4 x C2960X''s uplinked into 2 x 3850-12-XS-S core switches (stacked). The 2960''s are L2, and the 3850 is L3. My question is, do I need an IP DEFAULT GATEWAY statement on my
As a result, a handful of ports is usually enough for a core switch. Meanwhile, access switches often need a larger number of ports, and this is where you will
Inter-switch trunks should be an LACP bundle of at least two links for redundancy. Spread them across stack members so you don''t lose a closet if one member goes down. Build your topology as a tree,
Solved: Old legacy network and have 6 new switches that are to be used at access layer providing connectivity to end users. Is it recommended to move VLAN gateways from core switches
Gateways on Core Switch vs Firewall (MX250) I posted this in r/networking but thought it would be good to post here as well since my Firewalls are MX250 (HA pair). If anyone would be willing to share any
Do you really need the GWs on the cores? If you''re doing all the routing on the firewalls, it''s unnecessary to build a transit network between the fabric and the firewalls.
If you aren''t firewalling between internal VLANs and don''t plan to, I''d put those gateways on the core switches instead of the firewalls to save firewall load.
Will using the core as a gateway overburden it? Is it secure to place gateways at the access layer?After reading this article, you''ll be able to determine where and how to properly deploy
On Fortigate or core switches. In my research I''m getting mixed suggestions - Some say that core switches are for routing, when others say that core switches have to be as fast as possible and have
Probably a stupid question but when moving from a flat network to a tagged VLAN network, I know the core switch needs to have a default gateway of our firewall but what VLAN
Educational Core Switch vs. Edge Switch: What''s the Difference? Core switches and edge switches are two essential components that play distinct roles in the functioning of a network. This
In a Two-Tier architecture, the core switches provide IP gateways to downstream hosts, route traffic between data center hosts in different subnets, and route traffic between the data center
Yes, a layer 3 switch is much better at routing vlan traffic vs a firewall. Yes, you''ll need to add routes to your local subnets on the firewall. On the core
Is it better to have the default gateway locally at each branch (the 2920 at each office) with a route to the core, or to have an interface on the core layer 3 switch acting as the default
