Routing with a 2960 series switch

[al1p0ur]

  IOS 12.2(55)SE was released last Thursday for the 2960 switch (as well as others). With this release comes a HUGE enhancement, in my opinion, for the 2960 switch, layer 3 routing! This previously layer 2 only switch can now do basic static routing with the new SDM template in this version. No routing protocols are supported but this is a great boon for those of us with this switch who wanted this feature.
  You will notice that before upgrading the switch there is no ‘ip routing’ command:
   
 Switch(config)#ip rou?
  % Unrecognized command
  Switch(config)#ip rou
   
  Also, take note of the SDM templates that are available prior to 12.2(55)SE:
   
  Switch(config)#sdm prefer ?
    default             Default bias
    dual-ipv4-and-ipv6  Support both IPv4 and IPv6
    qos                 QoS bias
   
  Switch(config)#sdm prefer
   
  Now, with 12.2(55)SE installed, we will change our SDM template to the new ‘lanbase-routing’ template:
   
  Switch#show sdm prefer ?
    default             Default bias
    dual-ipv4-and-ipv6  Support both IPv4 and IPv6
    lanbase-routing     Lanbase routing
    qos                 QoS bias
    |                   Output modifiers
    
   
  Switch#show sdm prefer
   
   
  Switch(config)#sdm prefer lanbase-routing
  Changes to the running SDM preferences have been stored, but cannot take effect
  until the next reload.
  Use 'show sdm prefer' to see what SDM preference is currently active.
  Switch(config)#
   
  After a reload, let’s take a look at our SDM template:
   
  Switch#show sdm prefer
   The current template is "lanbase-routing" template.
   The selected template optimizes the resources in
   the switch to support this level of features for
   8 routed interfaces and 255 VLANs.
   
    number of unicast mac addresses:                  4K
    number of IPv4 IGMP groups + multicast routes:    0.25K
    number of IPv4 unicast routes:                    4.25K
      number of directly-connected IPv4 hosts:        4K
      number of indirect IPv4 routes:                 0.25K
    number of IPv4 policy based routing aces:         0
    number of IPv4/MAC qos aces:                      0.125k
    number of IPv4/MAC security aces:                 0.375k

  We can now enable IP routing:
   
  Switch(config)#ip routing
  Switch(config)#
   
  Great! It took the command. Let’s try adding a couple of routes…
   
  Switch(config)#ip route 0.0.0.0 0.0.0.0 172.20.2.1
  Switch(config)#ip route 10.99.1.0 255.255.255.0 172.20.2.11
  Switch(config)#ip route 10.100.1.0 255.255.255.0 172.20.2.11
  Switch(config)#end
  Switch#
  *Mar  1 00:07:46.305: %SYS-5-CONFIG_I: Configured from console by console
  Switch#show ip route
  Codes: C - connected, S - static, R - RIP, M - mobile, B - BGP
         D - EIGRP, EX - EIGRP external, O - OSPF, IA - OSPF inter area
         N1 - OSPF NSSA external type 1, N2 - OSPF NSSA external type 2
         E1 - OSPF external type 1, E2 - OSPF external type 2
         i - IS-IS, su - IS-IS summary, L1 - IS-IS level-1, L2 - IS-IS level-2
         ia - IS-IS inter area, * - candidate default, U - per-user static route
         o - ODR, P - periodic downloaded static route
   
  Gateway of last resort is 172.20.2.1 to network 0.0.0.0
   
       172.20.0.0/24 is subnetted, 1 subnets
  C       172.20.2.0 is directly connected, Vlan1
       10.0.0.0/24 is subnetted, 2 subnets
  S       10.99.1.0 [1/0] via 172.20.2.11
  S       10.100.1.0 [1/0] via 172.20.2.11
  S*   0.0.0.0/0 [1/0] via 172.20.2.1
  Switch#
   
  For more information, take a look at the release notes here as well as the new features section where you will notice the line item: “When you configure the new lanbase-routing SDM template, the switch supports static routing and router ACLs on SVIs. ( Catalyst 2960, 2960-S, and 2975)”.

فقط کسی تست کرده ببینه با بیش از 8 interface vlan هم کار میکنه یا نه و بین اونها هم IVR رو انجام میده یا نه ؟
چون صحبت از Max 8 Routed Interface کرده ! اگر منظور رو اشتباه متوجه نشده باشم
