Hi Naveen, Please refer the link for OSPF interface cost table for various interface types: http://www.watchguard.com/help/docs/edge/10/en-us/content/en-us/dynamicrouting/ospf_interface_cost_f.html However, suggest you explicity define the ospf cost on the interface in order to manage your primary and secondary links. Pls rate if helps ! Best Regards, Guruprasad R ... View more

Just to add more info to what Amit said, i recently deployed 4507 with Sup7-E and used 10G ports on it. It works perfect ! The good thing is, you can use them as 1G ports also based on your requriement. Best Regards, Guruprasad R ... View more

Hi, Workaround: If you have a /18 subnet then advertise 2 * /19 subnets into the Internet. Eg. 172.2x.0.0/18 is further divided into 172.2x.0.0/19 and 172.2x.32.0/19 Primary Ckt: Advertise  172.2x.0.0/19 with LP = 700 Advertise 172.2x.0.0/18 with LP = 500 Secondary Ckt: Advertise 172.2x.32.0/19 with LP = 700 Advertise 172.2x.0.0/18 with LP = 500 In this scenario, at Nomal circumstances, the traffic is equally load balanced. if the primary link fails, the 1st part of subnet (/19) will be still reached viz Secondary Ckt as they have next available longest-match which is /18 if the secondary link fails, the 2nd part of the subnet (/19) will be still reached viz Primary Ckt as they have next available longest-match which is /18 Pls rate if Helps!

HI, Is there cost explicitly specified for sending a packet on an interface of R1 using "ip ospf cost " If so, to reset the path cost to the default value, use the no form of this command. Pls Rate if Helps ! Best Regards, Guru Prasad R ... View more

Hello Kukreja, As said, purchase a APNIC IP Pool and route as below. Assume you have a requirement of /23 IP Pool for your Network and purchase the same from APNIC or RIPE based on your region/location. Divide the /23 IP Pool into 2" /24 IP networks: Viz ISP-A route as, 1st /24 as Primary /23 as Secondary Viz ISP-B route as, 2nd /24 as Primary /23 as Secondary In this case, if your ISP-A fails the next longest match for your network will be available viz ISP-B and vice versa. You can apply the same for multiple IP Pools unless and until it is purchased from the APNIC or RIPE. Please Rate if Helps ! Best Regards, Guru Prasad R ... View more

HI Nizam, Please refer link below, use BGP regular expression to control such kind of requirement, http://www.cisco.com/en/US/tech/tk365/technologies_tech_note09186a0080094a92.shtml Hope this Helps. Best Regards, Guru Prasad R. ... View more

HI Subodh, Let us assume the network setup as: PE1--P1--P2--P3--P4--PE2 Before we start, route-summarization is not recommended in the LSP path. Assume, the LSP path is between PE1-PE2. If the route-summarization is done at the P4 means, P4 advertises the summarized route to P3 & to its upstream neighbors. However, PE2 advertises non-summarized route to P4. In this case, P3 will see the route originated from the P4 (as summarised) and will do the Penultimate Hop Popping and deliver the Packet to P4 with VPN label only. Since the P4 will have no knowledge on the Packets with VPN label, it will just ignore it. In a normal scenario, the P4 has to do the Penultimate Hop Popping & deliver the packet to PE2. So, it is not recommended to go for route-summarization. Refer Question:3 on the useful link below: http://www.killtest.org/642-611.pdf Hope i am Informative. Pls RATE if HELPS Best Regards, Guru Prasad R. ... View more

HI Siva, Sample Config with N/W eg: PE3 ----> P ----> PE4 PE3: ---- mpls ldp neighbor 172.16.0.4 targeted ldp PE4: ---- mpls ldp neighbor 172.16.0.3 targeted ldp 1) Before the 'config' ensure the IGP reach ability between PE3-PE4 is Up & Running. 2) LDP between PE3-P & P-PE4 is Up & Running. Please see below some show output after successful configuration: From PE3: --------- PE3#sh mpls ldp nei Peer LDP Ident: 172.16.0.4:0; Local LDP Ident 172.16.0.3:0 TCP connection: 172.16.0.4.35909 - 172.16.0.3.646 State: Oper; Msgs sent/rcvd: 37/36; Downstream Up time: 00:00:10 LDP discovery sources: Targeted Hello 172.16.0.3 -> 172.16.0.4, active, passive Addresses bound to peer LDP Ident: 172.16.34.2 172.16.0.4 172.16.46.1 172.16.11.1 172.16.4.1 From PE4: --------- Peer LDP Ident: 172.16.0.3:0; Local LDP Ident 172.16.0.4:0 TCP connection: 172.16.0.3.646 - 172.16.0.4.35909 State: Oper; Msgs sent/rcvd: 38/41; Downstream Up time: 00:02:34 LDP discovery sources: Targeted Hello 172.16.0.4 -> 172.16.0.3, active, passive Addresses bound to peer LDP Ident: 172.16.0.3 172.16.34.1 172.16.36.1 172.16.10.1 172.16.3.1 Hope I am Informative, Pls Rate if HELPS Best Regards, Guru Prasad R. ...
