Hi Pro, In ASR1k, is it possible to build an aggregate service policy that limit the total bandwidth (either inbound or outbond) utiliztation of a group of sub-interfaces? I have a customer who has 3 circuits terminating on 3 of the tens of sub-interfaces. I need to limit a total of 30M bandwidth to this customer. Is there way to achieve this? Thanks in advance. Larry

Hi, My SolarWinds NPM shows very high memory utization (up to 99%) on all ASR1001. CLI outpu belows confirms this: ---------------sh platform software status control-processor br Load Average Slot Status 1-Min 5-Min 15-Min RP0 Healthy 0.11 0.29 0.29 Memory (kB) Slot Status Total Used (Pct) Free (Pct) Committed (Pct) RP0 Healthy 3944728 3906172 (99%) 38556 ( 1%) 3801056 (96%) CPU Utilization Slot CPU User System Nice Idle IRQ SIRQ IOwait RP0 0 2.80 2.90 0.00 94.29 0.00 0.00 0.00 1 3.60 5.60 0.00 90.80 0.00 0.00 0.00 -------------------------------------------------------------- Is this considered 'healthy' as in shown in the output? Thanks. Larry

Thanks for the comment. I got back from my SP that they provide the wrong number. 256kbps is the Be value, not the Bc. Best regards. larry

Hi, My SP has an ingress policer specifying 100mbps CIR and 256kbps Bc. When I try to configure a shaper to match this requirement, I cannot specify a Bc value smaller than 400000, as the Tc cannot be less than 4ms. For example, ---------------------------------------------------------------------- OFFICE-01(config-pmap-c)#policy-map policy-map QoS-Outbound-100M OFFICE-01(config-pmap-c)#class class-default OFFICE-01(config-pmap-c)#shaper average 100000000 265000 Shaping Interval is 3 milliseconds. Intervals below 4 milliseconds rejected. --------------------------------------------------- If I use the minimum Bc value of 400000bps, traffic might be dropped by the SP. Any workaround? The major application in the network is http. Thanks. Larry

Hi, I have an ASR1001 showing very high memery utilization in the last 8 months. SolarWinds shows 94% all the time. The top 3 processes using the memory are: linux_iosd-imag (25.9%), fman_rp (21.4%) and fman_fp_image (17.4). The first is for the IOS image. What are the other 2?

Hi Danny, It is hard to say what is wrong with your setup without running debug commands. I have set up a lab with one C887va and one C888E, and successfully running L2TPv3. The relevant part of the config in C887 is as follows. I am using advipservices: c880data-universalk9-mz.152-1.T.bin. ------------------------ l2tp-class L2_CL hello 10 password 7 02050D480809 !----->same on both ends cookie size 8 ! pseudowire-class L2TPv3_PS encapsulation l2tpv3 interworking ethernet !---->you missed this in your config protocol l2tpv3 L2_CL ip local interface Ethernet0.10 !---->source layer3 interface ip dfbit set ! interface Vlan1 xconnect A.B.C.D 100 encapsulation l2tpv3 pw-class L2TPv3_PS !----->destination IP address ---------------------------------------- The following commands can be used for checking: show xconne all detail show l2tp session show l2tp tunnel Hope this be helpful to you.

Hi Antonio, This is not possible. Think of one PC, say, 172.16.0.1. When it browses one website, it has a dynamic source port; when it opens another TCP/IP session to outside world, another dynamic source port is used, and so on. These concurrent sessions are working because the NAT router dynamically maps ports. One port on the NAT router maps to only one port on an inside ip address. Regards.

Hi Jerhone, Where are you doing NATting? On Router 0 and Router 1? Then my suggestions are as follows: 1. Remove the key word "always" in the command "default-information originate always", so that OSPF will advertise a default only when it has a default route; Adjust the metric so that one of the routers is the primary router. 2. On both routers, use "ip route 0.0.0.0 0.0.0.0 x.x.x.x track x" command to install a default route only when tracking is successfull; 3. Adjust the tracking timers agressively to achieve fast convergence; 4. Adjust OSPF timers to the possible lowest values. If no NATting is involved, you will mostly depend on ISP routers' BGP timers for convergence because your subnets have to be advertised out to ISP for returning traffic. Hope this helps.

Hi, One of the ASR1001 routers has the following configs. The other 2 ASR1001 have similar configs. OSPF between CE's are not forming adjacency unless I manaually set the ospf network type to 'nonbroadcast' and use 'neighbor' commands. RIP and eigrp are not working either. Multicast traffic simply does not go through the VPLS. I tried using vfi auto discovery but failed even for unicast traffic. Regards. Thanks. ------------------------------------------------------------------ bridge-domain 101 l2 vfi TEST manual vpn id 11 bridge-domain 101 neighbor 172.16.33.15 102 encapsulation mpls neighbor 172.16.33.2 102 encapsulation mpls ! ! interface GigabitEthernet0/0/0 mtu 9216 no ip address load-interval 30 negotiation auto cdp enable service instance 101 ethernet encapsulation dot1q 101 rewrite ingress tag pop 1 symmetric bridge-domain 101 ! -------------------------------------------------------------

Hi All, I have a dozen of ASR's and having LDP problem between two of them: one ASR1006 and one ASR1001 over an inter-metro WAN. The LDP session is broken every now and then, even though the OSPF between them has no adjacency issues. All other LDP sessions between the adjacent routers are working fine. Here is the LDP discovery details when the session is down. Both are transmitting hellos but neither are receiving. What are the possible causes of this? How to troubleshoot? We initially thought of the IOS issue, but have upgraded from 15.1(2)S1 to 152-2.S without resolving the problem. -----------------------------------------------In ASR1001: sh mpls ldp discovery d Local LDP Identifier: 172.16.33.3:0 Discovery Sources: Interfaces: GigabitEthernet0/0/0.1 (ldp): xmit <-------------problem session Enabled: Interface config Hello interval: 5000 ms; Transport IP addr: 172.16.33.3 Clients: IPv4 GigabitEthernet0/0/0.2 (ldp): xmit/recv Enabled: Interface config Hello interval: 5000 ms; Transport IP addr: 172.16.33.3 LDP Id: 172.16.33.4:0 Src IP addr: 172.16.32.10; Transport IP addr: 172.16.33.4 Hold time: 15 sec; Proposed local/peer: 15/15 sec Reachable via 172.16.33.4/32 Password: not required, none, in use Clients: IPv4 GigabitEthernet0/0/0.3 (ldp): xmit/recv Enabled: Interface config Hello interval: 5000 ms; Transport IP addr: 172.16.33.3 LDP Id: 172.16.33.8:0 Src IP addr: 172.16.32.29; Transport IP addr: 172.16.33.8 Hold time: 15 sec; Proposed local/peer: 15/15 sec Reachable via 172.16.33.8/32 Password: not required, none, in use Clients: IPv4 -----------------------------------------------In ASR1006: sh mpls ldp discovery d Local LDP Identifier: 172.16.33.1:0 Discovery Sources: Interfaces: GigabitEthernet0/0/0 (ldp): xmit/recv Enabled: Interface config Hello interval: 5000 ms; Transport IP addr: 172.16.33.1 LDP Id: 172.16.33.2:0 Src IP addr: 172.16.32.2; Transport IP addr: 172.16.33.2 Hold time: 15 sec; Proposed local/peer: 15/15 sec Reachable via 172.16.33.2/32 Password: not required, none, in use Clients: IPv4 GigabitEthernet0/0/7.1 (ldp): xmit <---------------problem session Enabled: Interface config Hello interval: 5000 ms; Transport IP addr: 172.16.33.1 Clients: IPv4 GigabitEthernet0/0/7.2 (ldp): xmit/recv Enabled: Interface config Hello interval: 5000 ms; Transport IP addr: 172.16.33.1 LDP Id: 172.16.33.10:0 Src IP addr: 172.16.32.37; Transport IP addr: 172.16.33.10 Hold time: 15 sec; Proposed local/peer: 15/15 sec Reachable via 172.16.33.10/32 Password: not required, none, in use Clients: IPv4 Thanks in advance.
