Hi guys,
first of all i will describe my topology, PE---RR---P(eBGP)--P(eBGP). I have the following issue, when any prefix "vpnv4" I receive via eBGP flaps, the label assigned to that prefix change, but I don´t see that change in the PE, so I need to do a clear ip cef... . This happened only with prefix receive via eBGP. Do you have any idea????

Thanks a lot!!

Hi Guys,
I need to find out whether there is any Cisco 10 Gigabit Ethernet card
that supports EoMPLS. I spent hours and hours on Cisco.com but I could
only confirm that only OSM modules might supports EoMPLS.

Mathias

What exactly do you mean by "support eompls"?
In the broadest possible sense, 10 gig LAN line card for 6500/7600 supports
EoMPLS, with all limitations as other LAN line cards.

All 7600 cards support EoMPLS. For EoMPLS on SVIs, you need OSM/SIPs
facing the MPLS-core.

Sorry what I meant was VPLS support or point to multipoint TLS. Is this
supported on 10G card?

EoMPLS, with all limitations as other LAN line cards.

So "unicast" and "labeled-unicast" are not mutually exclusive, as the doc
suggests (at least in JUNOS 7.4R2.6).
Of course, if You don't want all inet.3 to be advertised then You can filter
out unwanted prefixes outbound from Juniper by applying export policy.

I will risk and say that it isn't (as uplink), but I have not taken a look
into recent features.

Hi guys,
How can I increase a catalyst 2950 vlan database? Currently the maximum
capacity is 64. Will an IOS image upgrade help?

Is it possible to encapsulate X.25 in IP? If yes how can that be
accomplished using a cisco router and which routers are capable?

As of 12.1(22)EA7, the standard-image 2950s can support up to 128 Vlans. It was
quite a pleasant surprise :)
